Review
Excellent control result. A clearly drawn white pelican with a big orange pouch sits on a red road bike with spokes, chainring and chain, a front basket with a fish, feet on the pedals and a wing on the bars, set on a sunny path with clouds.
The full review
Excellent control result. A clearly drawn white pelican with a big orange pouch sits on a red road bike with spokes, chainring and chain, a front basket with a fish, feet on the pedals and a wing on the bars, set on a sunny path with clouds. Clean, confident flat illustration; it checked its own renders and fixed the leg geometry.
Verdict by the AI judge (provisional).
OK. Finished on its own after 16.1 min and produced pelican.svg.
Bugs
- Saddle is hidden under the body, so the seating contact is implied rather than drawn
- Wing reads as a large white blob at thumbnail size

- AI judge
- AI judge: the test runner (model claude-opus-5-5), scoring by visual review of the 1600 px render against the pre-registered rubric. A draft score until the reviewer checks it. Rubric: Wave-1 SVG scoring rubric (AI Model Reviewer).
- Visitors
- Public voting with a blind reveal is coming: you score the output first, then see the other scores.
- Reviewer
- The reviewer's own grade appears here once it is added.
Scores compare results for the same prompt only. AI-judge boards rank runs within one prompt, equal totals sharing a rank; scores from different prompts are never averaged.
