Chalkboard Menu
Text-to-Image“Handwritten-style chalkboard menu in a cozy café, all text rendered in the exact same realistic chalk handwriting style with natural variations in letter size, slight slant, and chalk texture — no printed or digital fonts anywhere on the board. Title at the top in elegant cursive chalk handwriting: ‘TODAY’S SPECIALS – APRIL 30, 2026’. Below it, three menu items also in the same handwritten chalk style: ‘Truffle Mushroom Risotto – $24’, ‘Grilled Octopus with Lemon & Herbs – $28’, ‘Brown Butter Chocolate Chip Cookies – $9’. At the very bottom, smaller text in the identical handwritten chalk style (slightly smaller but still clearly legible with the same handwriting characteristics): ‘All items made fresh daily • Ask about our gluten-free options’. Warm ambient café lighting, visible chalk dust and smudges, realistic handwriting imperfections, no clean printed text anywhere.”
AI Judge Analysis
Nano Banana
- + Excellent authentic chalk texture with realistic powdery edges
- + Perfectly rendered handwriting that matches the requested 'natural variations'
- + Highly realistic lighting and depth-of-field within a cafe environment
- − The perspective makes the leftmost text slightly harder to read
- − The title is in print-script rather than the requested 'elegant cursive'
Wan 2.7
- + Perfect text accuracy and completion of the cut-off prompt
- + Very clear and centered composition
- + Included decorative chalk lines which add to the menu feel
- − The text looks like a digital font rather than natural handwriting
- − Lacks the realistic grainy chalk texture requested in the prompt
- − The 'glow' around the text feels synthetic
Verdict: Nano Banana captures the requested 'handwritten-style' and 'chalk texture' perfectly, resulting in an image that looks like a real physical object. While Wan 2.7 has superior text legibility and followed the specific 'elegant cursive' instruction for the title better, its rendering looks like a digital overlay or a font, failing the primary texture requirements of the prompt.
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
- + Successfully copied the exact clothing (coat and plaid scarf) from Image 2
- + Maintained the facial features and hair of the subject perfectly
- + Successfully integrated the hand and watch from Image 2 onto the subject
- − The neck area is poorly blended, showing a harsh line where the new body meets the original head
- − The clothing scale and pose are borrowed directly from Image 2 rather than being adapted to the pose in Image 1
Wan 2.7
- + Successfully adapted the subject to a full standing pose that fits the environment
- + Preserved the face and unique skin patterns of the subject well
- − Completely failed to use the clothing from Image 2, generating a fantasy-style robe instead
- − The scale of the subject in the background feels slightly detached from original image proportions
Verdict: Nano Banana followed the outfit instructions perfectly, transferring the exact coat and scarf from Image 2, though the blending at the neck is unrefined. Wan 2.7 failed the primary instruction of the task by replacing the requested outfit with a completely different, hallucinated style. Nano Banana is the clear winner for maintaining fidelity to the provided source images.
The Capybara Taxi Driver
Text-to-Image“Photorealistic scene inside a yellow New York taxi at night. A capybara is driving, wearing a yellow taxi driver cap and a dark jacket. It has a calm, professional expression and both front paws on the steering wheel. In the back seat sits a human businesswoman in a coat, looking at her phone with a completely normal, bored expression (as if this is just another normal ride). Through the windows you can see the streets of Manhattan at night with blurred lights. Realistic taxi interior, photorealistic, detailed fur and fabric, 35mm lens, night lighting with reflections, shallow depth of field.”
AI Judge Analysis
Nano Banana
- + Excellent fur texture rendering
- + Cinematic lighting consistent with a New York night
- + Strong composition with clear focus on the subject and passenger
- − The passenger is sitting in the front passenger seat instead of the back seat
- − The capybara only has one paw clearly on the wheel
Wan 2.7
- + Successfully places the human passenger in the back seat as requested
- + Includes both front paws on the steering wheel
- + Higher clarity and sharpness across the entire frame
- − The capybara's head looks somewhat pasted onto the body
- − The lighting on the capybara's face is a bit flat compared to the background environment
Verdict: Wan 2.7 is the winner because it followed the spatial instructions more accurately, placing the businesswoman in the back seat and showing both paws on the wheel. Nano Banana produced a more moody, cinematic image, but failed the specific layout requirement by putting the passenger in the front seat.
The Halloween Invitation
Text-to-Image“Vintage gothic Halloween party invitation. Dark parchment poster, spooky border with webs and thorns, central glowing jack-o-lantern, bats, twisted trees, moody night sky. Add elegant gothic title text saying "Halloween Party Invitation", a small scroll banner saying "You are invited to a night of frights", and event details at the bottom: Date: 30.10.2026 Time: 7pm Location: The Arches, NYC Spooky but polished, cinematic lighting, square format.”
AI Judge Analysis
Nano Banana
- + Excellent atmospheric cinematic lighting and mood
- + Very crisp and accurate text rendering for all requested details
- + Sophisticated gothic border design with integrated skulls and webs
- − The parchment texture is a bit flat compared to the illustration
- − The central jack-o-lantern is a bit generic in style
Wan 2.7
- + Rich, detailed illustration style with extra thematic elements like the cauldron and books
- + Beautifully rendered scroll banner and elaborate vine/thorn border
- + Strong vintage storybook aesthetic
- − The main title 'Halloween Party Invitation' has slight lettering inconsistencies in the font
- − The composition feels a bit crowded with the nested rectangular frame
Verdict: Both models followed the prompt exceptionally well, including all requested text and specific design elements. Nano Banana wins on clarity and professional layout, providing a very polished invitation feel, while Wan 2.7 offers a more vibrant and detailed illustration style that captures the 'vintage' aspect through a classic book-plate look.
