Judge & Evaluator
The winner of this SVG challenge is Claude Opus 4 Thinking (2025-05-14) Player 2

Judge's Analysis

    Player 2's submission demonstrates superior creativity, technical quality, and adherence to the prompt.

    The composition is visually engaging, with a well-detailed snail and rocket on a vibrant rainbow road, set against a starry background.

    In contrast, Player 1's submission lacks detail and polish, making it less visually appealing and immersive.

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.

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.
