Judge & Evaluator
The winner of this SVG challenge is
GPT-4.1 (2025-04-14)
Player 2
Judge's Analysis
Player 2's submission is more detailed, creative, and visually appealing, with a clear depiction of an alien juggling planets under a double rainbow.
The use of vibrant colors, smooth gradients, and whimsical design effectively adheres to the prompt.
Player 1's submission lacks detail and does not fully convey the theme of the prompt.
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.

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

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.
