Man and Car in California
Editing“Make a photo of the man driving the car down the California coastline”
AI Judge Analysis
Nano Banana
- + Perfectly preserves the specific Rolls-Royce model from the source image.
- + Includes the man from the source image sitting in the driver's seat.
- + Excellent background integration with realistic motion blur and coastal scenery.
- − The man is quite small in the frame and lacks some of the detail from the source.
Qwen Image Edit 2511
- + Excellent subject preservation, keeping the man's face, hair, and outfit almost identical to the source.
- + High quality interior detail that matches the Rolls-Royce aesthetic.
- + Captures the 'California' vibe well with the addition of palm trees.
- − The car interior is somewhat generic and doesn't explicitly preserve the unique dashboard/steering wheel of the original Rolls-Royce.
- − The perspective change is more drastic than Model A.
Verdict: Both models succeeded at a difficult multi-image composition task. Nano Banana is the better choice for car enthusiasts as it perfectly preserves the exact Rolls-Royce model and silhouette, placing it naturally in the environment. Qwen Image Edit 2511 is superior for subject portraiture, as it keeps the man's identity and specific clothing much clearer, though it sacrifices some accuracy on the vehicle's specific interior design.
Pose & Character Mashup
Editing“Use Image 1 as the exact pose reference and Image 2 as the character reference. Recreate the person/character from Image 2 in the exact dynamic pose and body position from Image 1. Keep the exact face, hair, clothing style/details, and expression from Image 2. Match the lighting and environment of Image 1. The final image must show the character from Image 2 performing the precise action/pose from Image 1 with perfect anatomy and natural integration.”
AI Judge Analysis
Nano Banana
- + Successfully integrated clothing elements like the black sweatshirt, scarf, and sunglasses from Image 2 onto the character.
- + Maintained the exact pose and yellow environment from Image 1.
- + The clothing text and scarf patterns are rendered realistically onto the existing person's frame.
- − Failed to swap the person's face/identity, keeping the woman from Image 1 instead of the man from Image 2.
- − The sunglasses are poorly blended onto the face with visible artifacts.
Qwen Image Edit 2511
- + Maintained the original character's face and appearance in the background.
- + Preserved the red color of the sweatshirt from Image 1.
- − Failed the primary task by overlaying Image 1's subject on top of Image 2 instead of merging the identities.
- − Anatomy of the feet and legs is severely distorted where they meet the red box.
- − The composition is a messy collage rather than a recreated character/pose.
Verdict: Both models struggled with the complex instruction to merge a specific identity onto a specific pose. Nano Banana was more successful in creating a coherent single image that transferred the clothing and accessories of the target character onto the pose, though it failed to change the person's face. Qwen Image Edit 2511 simply combined the two images into a poor-quality collage with significant anatomical errors, making Nano Banana the preferred choice for its visual consistency.
Outfit Transfer Challenge
Editing“Use Image 1 as the base person. Dress them in the exact elaborate outfit from Image 2 (including all layers, accessories, jewelry, and shoes). Carefully adapt the clothing to the body shape and pose in Image 1 while maintaining realistic fabric behavior, correct proportions, and perfect lighting/shadow matching. Keep the person’s exact face, hair, and background completely unchanged.”
AI Judge Analysis
Nano Banana
- + Excellent preservation of the source person face and unique skin features
- + Background remains perfectly identical to the original
- + Realistic fabric texture on the coat
- − Failed to dress the person, and instead hung the coat behind/beside them
- − Only transferred parts of the outfit, missing the jeans and shoes
- − Incorrect scarf pattern color (red instead of dark teal/green)
Qwen Image Edit 2511
- + Successfully applied the full outfit including coat, scarf, jeans, sunglasses and shoes
- + Maintains the exact scarf pattern and color from the reference image
- + Excellent lighting and shadow integration with the original background
- − Completely changed the person's face and hair, failing the primary preservation requirement
- − Lost the unique skin features (vitiligo) of the person from Image 1
- − Modified the pose significantly to match Image 2's vibe
Verdict: This comparison highlights the struggle between subject preservation and complex clothing transfer. Nano Banana is the better choice because it successfully followed the 'keep the person's exact face, hair, and background completely unchanged' instruction, even though it failed to correctly 'dress' the subject, whereas Qwen Image Edit 2511 essentially replaced the person from Image 1 with the person from Image 2.
Bald man challenge
Image Editing“Give the person a full, thick head of natural hair with realistic texture, density, and a natural hairline. Preserve facial features and lighting.”
AI Judge Analysis
Nano Banana
- + Excellent preservation of the original facial features and skin texture.
- + The hairline looks natural and blends well with the existing forehead skin.
- + Matches the hair color and texture perfectly to the person's existing beard.
- − The hair volume is slightly conservative compared to the request for 'full, thick' hair.
Qwen Image Edit 2511
- + Successfully added a very full and thick head of hair.
- + Maintains the background and clothing from the original image effectively.
- − The hair texture has a plastic, 'AI-generated' sheen that looks unnatural.
- − The hairline is too low and creates a strange overlap with the glasses' temple.
- − The facial features have been slightly smoothed or altered compared to the original.
Verdict: Nano Banana followed the instructions much more effectively by creating a realistic, believable hairstyle that matches the subject's existing beard and natural hairline. Qwen Image Edit 2511 provided more volume, but the hair looks like a poorly blended wig with a synthetic texture, and it negatively impacted the realism of the facial features.
Over-the-top cartoon caricature
Editing“Create a caricature of me and my job. Make it exaggerated and humorous, incorporating my profession as a tv show anchor and my love for dogs and hockey.”
AI Judge Analysis
Nano Banana
- + Successfully incorporates all three elements: TV anchor, dogs, and hockey.
- + The 'Puck News Network' theme and dog hockey audience are very creative.
- + Maintains a clear likeness to the original subject while applying caricature distortion.
- − The fingers holding the newspaper are slightly garbled.
- − Text on the newspaper and score board is somewhat messy compared to the main title.
Qwen Image Edit 2511
- + Strong, clean line art style characteristic of modern caricatures.
- + Preserves the subject's smile and facial features well in a cartoon format.
- − Completely missed the 'hockey' requirement of the prompt.
- − The speech bubble contains nonsensical gibberish text.
- − Strange artifacts like a candle on the desk and a floating hand gesture.
Verdict: Nano Banana followed the prompt much more effectively by creatively blending all of the user's interests (TV news, hockey, and dogs) into a single cohesive scene with a clear 'Puck News Network' theme. Qwen Image Edit 2511 produced a clean caricature illustration but entirely failed to include the hockey elements and featured more nonsensical details like garbled text and a random candle. Nano Banana's inclusion of a dog hockey crowd and score board makes it the clear winner for prompt adherence.
Studio Ghibli Anime Style
Editing“Transform this photo into a Studio Ghibli–inspired illustration. Use soft pastel colors, hand-painted textures, gentle lighting, dreamy backgrounds, and a warm, nostalgic mood”
AI Judge Analysis
Nano Banana
- + Subtly softens the lighting and skin textures.
- + Maintains the exact geometry and proportions of the original photo.
- − Failed to transform the photo into an illustration style.
- − Does not exhibit typical Studio Ghibli artistic traits like hand-painted backgrounds or line art.
- − The blurred foreground figure is inconsistent with the requested animation style.
Qwen Image Edit 2511
- + Successfully applied a clear illustration style with linework and hand-painted textures.
- + Exhibits the requested Studio Ghibli palette of soft pastels and dreamy lighting.
- + Maintains excellent preservation of the original pose, expressions, and clothing details.
- − Minor facial structural changes make the characters look slightly different from the source photo.
Verdict: Nano Banana failed to complete the core instruction, providing what looks like a slightly airbrushed photo rather than an illustration. Conversely, Qwen Image Edit 2511 followed the prompt perfectly, delivering a high-quality Ghibli-esque transformation that maintains the humor and composition of the original meme. Qwen's attention to artistic style, using clean lines and a painterly background, makes it the clear winner.
Golden Hour Stroll
Image Editing“Add dynamic motion to this photo: make hair blow in the wind, add leaves flying, energetic and lively feel.”
AI Judge Analysis
Nano Banana
- + Excellent adherence to the request for blowing hair and flying leaves.
- + Maintains very high identity preservation of the woman and the dog.
- + The leaves have a natural, scattered appearance with varied sizes.
- − The leash has a slight alignment artifact where a leaf overlaps it.
- − Some leaves look a bit like static stickers rather than having motion blur.
Qwen Image Edit 2511
- + High energy in the hair movement with a more symmetrical, 'windy' effect.
- + Good preservation of the background elements and the overall scene structure.
- + Incorporates green leaves which contrast well with the existing foliage.
- − The hair has some structural artifacts and looks slightly disconnected from the head.
- − The dog's tail has a strange, smudged texture at the base.
- − The woman's facial features changed slightly compared to the source image.
Verdict: Nano Banana followed the instructions more effectively while preserving the original quality of the source image. Qwen Image Edit 2511 created a more dramatic hair effect, but it introduced small visual artifacts and slightly altered the woman's face, making Nano Banana the more reliable edit.
