Judge & Evaluator
The winner of this SVG challenge is
GPT-4.1 (2025-04-14)
Player 1
Judge's Analysis
Player 1's submission showcases a more detailed and visually appealing depiction of the prompt, with a well-designed astronaut, a clear watermelon slice, and a space background filled with small stars and objects adding depth.
Player 2's submission, while adhering to the prompt, lacks the same level of detail and creativity, with a simpler, less refined composition that feels incomplete by comparison.
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.

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.
