AI Judge Analysis
Seedream 4.0
- + Atmospheric, cinematic lighting with a realistic 3D feel.
- + Rich, moody textures on the parchment and jack-o-lantern.
- + Excellent integration of the thorny border with the background scenery.
- − Text on the small scroll banner is quite blurry and difficult to read.
- − Composition is a bit cluttered around the central text area.
Wan 2.7 Pro
- + Clear, legible text across all intended fields including the scroll.
- + Clean, illustrative design with symmetrical composition.
- + Rich in specific thematic details like the cauldron, gravestones, and roses.
- − The jack-o-lantern's green color and candle-nose are a slightly odd interpretation of a 'glowing jack-o-lantern'.
- − Lighting feels flatter and less 'cinematic' than Model A.
Verdict: Seedream 4.0 excels at creating a moody, atmospheric image with superior lighting and texture, making it feel like a high-end cinematic poster. However, Wan 2.7 Pro is much more effective at rendering the specific text details requested in the prompt, providing a cleaner and more professional layout for an actual invitation. While Seedream 4.0 is more visually striking, Wan 2.7 Pro is the more functional design.
