Man and Car in California
Editing“Make a photo of the man driving the car down the California coastline”
AI Judge Analysis
Qwen Image Edit 2511
- + Excellent preservation of the subject's face and hair details
- + Perfectly recreates the specific plaid pattern of the coat
- + High visual quality with realistic lighting and interior details
- − Changes the car model internally (dashboard/steering wheel no longer match a Rolls-Royce)
Seedream 4.0
- + Strongly preserves the exterior model of the original car (Rolls-Royce Phantom Drophead Coupe)
- + Excellent composition capturing the movement of the car on the coastline
- + Good integration of the driver into the scene
- − Loss of fine detail in the subject's face and hair
- − The plaid pattern of the coat is significantly simplified and altered
Verdict: This is a close competition between two different approaches. Qwen Image Edit 2511 focuses on preserving the man's identity and clothing with incredible accuracy, although it sacrifices the specific car model's interior details. Seedream 4.0 does a better job of preserving the car's exterior identity and the sense of motion, but lose the likeness of the man and the detail of his outfit. Qwen Image Edit 2511 is the winner for its superior rendering of the subject's face and textures.
Bald man challenge
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
Qwen Image Edit 2511
- + Excellent texture and realistic hair volume
- + Very natural integrated hairline
- + Perfectly preserved the background and lighting
- − Subtle change to the eye/brow region makes the face look slightly different from the source
Seedream 4.0
- + Successfully added a full head of hair
- + Maintained the face shape and character well
- − Hair texture looks slightly fuzzy or synthetic compared to the sharp beard
- − The hairline is very straight and lacks a natural recession or transition
- − Lower technical resolution on the hair fibers
Verdict: Qwen Image Edit 2511 produced a much more realistic result with convincing hair texture and a believable hairline, though it slightly softened some facial details. Seedream 4.0 successfully followed the prompt but the hair appears somewhat like a wig due to its uniform texture and lack of a natural transition at the forehead.
Night Sky Transformation
Editing“Change the scene to night: a deep, dark sky with subtle, glistening stars visible behind the mountain.”
AI Judge Analysis
Qwen Image Edit 2511
- + Excellent preservation of the original image details and town structure.
- + Successfully transitions the lower half of the scene into a darker, night-time atmosphere.
- − The sky has a very artificial, pattern-like grid of stars that looks like a low-quality texture overlay.
- − There is a logical inconsistency with the peak of the mountain remaining brightly lit by a sunset glow that no longer exists in the sky.
Seedream 4.0
- + Provides a much more realistic and 'glistening' star field that feels integrated into the scene.
- + Achieves a more coherent night-time lighting balance across the entire image.
- − The peak of the mountain still retains a warm glow, though it is more muted than in the source.
- − Slight loss of sharpness in the town's streetlights compared to the source.
Verdict: Seedream 4.0 is the clear winner because it produces a realistic night sky with subtle, natural-looking stars, whereas Qwen Image Edit 2511 uses a distracting, repetitive dot pattern for the stars. Seedream 4.0 also does a better job of harmonizing the overall lighting of the scene while maintaining the integrity of the original landscape.
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
Qwen Image Edit 2511
- + Excellent preservation of the original subjects' facial features and expressions
- + Accurate reproduction of the clothing patterns, specifically the plaid shirt
- + Maintains the depth and complexity of the urban background
- − The art style leans more towards generic digital manhwa/anime rather than the specific Studio Ghibli aesthetic
- − The addition of sparkles feels a bit distracting and not characteristic of the requested style
Seedream 4.0
- + Perfectly captures the Studio Ghibli 'watercolor' and hand-painted texture look
- + Uses the soft pastel palette and dreamy lighting requested in the prompt
- + Excellent translation of the characters into the simplified anime character designs associated with the studio
- − Sacrifices the specific facial identities of the people in the original image for generic character faces
- − The background detail is almost entirely lost in favor of a watercolor wash
Verdict: Seedream 4.0 followed the stylistic instructions much more accurately, producing a result that truly feels like a Studio Ghibli watercolor illustration, despite losing the likeness of the original subjects. Qwen Image Edit 2511 preserved the original image details and identities much better but failed to fully capture the distinctive Ghibli art style, resulting in a more generic digital illustration.

AI Judge Analysis
Qwen Image Edit 2511
- + Excellent preservation of the original image's identity and background pixels
- + Accurately rendered subtle eye crinkles and lifted cheeks
- + Natural skin texture and lighting consistency
- − Did not show teeth as requested in the 'natural teeth' instruction
Seedream 4.0
- + Successfully included natural teeth as requested
- + Stronger overall change to the expression while maintaining identity
- + Very convincing Duchenne eye crinkles
- − Slightly altered the shape of the nose and the density of freckles compared to the original
- − Minor loss of high-frequency skin texture/pores compared to the source
Verdict: Both models performed exceptionally well at maintaining the subject's identity while altering the expression. Seedream 4.0 followed the prompt more closely by including the requested 'natural teeth', whereas Qwen Image Edit 2511 opted for a closed-mouth smile but achieved superior preservation of the original skin texture and background details.
Golden Hour Stroll
Editing“Add dynamic motion to this photo: make hair blow in the wind, add leaves flying, energetic and lively feel.”
AI Judge Analysis
Qwen Image Edit 2511
- + Excellent adherence to the 'hair blowing in the wind' instruction
- + Bright and colorful leaves add high energy to the scene
- + Perfectly preserves the woman's face and original clothing
- − Hair strands look a bit stiff and vectorized rather than natural
- − The dog's tail has a slightly awkward jagged edge after the edit
Seedream 4.0
- + The hair motion looks more realistic and natural
- + Good overall preservation of the source image colors and lighting
- − The woman's facial features were altered, losing the likeness of the original
- − The flying leaves are subtle and less energetic compared to the other model
Verdict: Qwen Image Edit 2511 followed all instructions perfectly, creating a high-energy scene while maintaining the exact likeness of the original subject. Seedream 4.0 provided more natural-looking hair movement, but it failed to preserve the woman's face correctly and the overall impact of the added motion was less dynamic.
