Judge & Evaluator
The winner of this SVG challenge is
Claude Sonnet 4 (2025-05-14)
Player 2
Judge's Analysis
Player 2's submission is more visually dynamic with a vibrant color palette, a detailed bending rainbow, and a starry background that enhances the setting.
The snail and rocket are more stylized and imaginative, adhering closely to the prompt while maintaining stronger technical quality and visual appeal compared to Player 1's simpler composition.
These metrics analyze technical aspects of both SVG drawings. Look for differences that might explain the judge's decision. Use the "View Code" button above to see the SVG code for each drawing.

AI Judging Process
Creativity
Originality, innovative use of shapes and unique approach to the prompt.
Prompt Adherence
How accurately the SVG captures the essence of the prompt.
Visual Appeal
Aesthetic quality including composition, color usage and overall visual impact.
How does judging work?
SVG drawings are converted to static PNG images for evaluation. The AI judge receives the original prompt and both images, then determines which drawing better fulfills the evaluation criteria without seeing animations, interactivity, or SVG code.
