Judge & Evaluator
The winner of this SVG challenge is
GPT-4.1 (2025-04-14)
Player 1
Judge's Analysis
Player 1's submission features a clear and vibrant depiction of a flying whale with rainbow wings, fully capturing the whimsical and futuristic essence of the prompt.
The background and cityscape are well-integrated, adding visual depth.
Player 2's submission, while creative, lacks the same level of detail and visual harmony, with the whale and cityscape appearing more simplistic and disconnected.
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.
