Judge & Evaluator
The winner of this SVG challenge is
Gemini 2.5 Pro Preview 05-06
Player 2
Judge's Analysis
Player 2's submission is more detailed, colorful, and closely adheres to the prompt with a clear depiction of both a snail and a rocket racing under a vibrant rainbow.
The composition is dynamic and visually appealing, with elements like the finish line and motion effects adding creativity.
Player 1's submission, while creative, lacks clarity in illustrating the concept of a race or a rocket, and the overall execution feels less polished.
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.
