Evaluation criteria
- Check identity first: face shape, eye spacing, hairline, and other stable traits should survive the requested scene.
- Then check prompt adherence: pose, wardrobe, camera angle, lighting, and background details should match the same written brief.
- Inspect anatomy and artifacts at full size rather than judging from the thumbnail crop.
- Do not treat one output per model as a reliability estimate; rerun prompts from your own character before changing a production default.
