Judge & Evaluator
The winner of this SVG challenge is
Claude Sonnet 4 Thinking (2025-05-14)
Player 2
Judge's Analysis
Player 2's submission demonstrates superior creativity and technical quality with more detailed and vibrant jellyfish, a richer color gradient in the sky, and a stronger sense of depth.
The composition feels more immersive and visually appealing, closely aligning with the concept of towering jellyfish at sunset.
Player 1's effort is charming but lacks the same level of detail and dynamic execution seen in Player 2's work.
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.
