AI kitbash pack is a starting point, not proof that an asset is production-ready. A proportion review pass should distinguish generation artifacts from deliberate form before anyone spends time polishing the result.
For AI kitbash pack, keep the proportion review pass focused on silhouette, symmetry, and scale references. Make one controlled change at a time and retain enough evidence for another person to repeat the decision.
Compare silhouette, symmetry, scale references, and landmark placement before local sculpting makes structural errors harder to fix. Apply this proportion review guidance to the actual AI kitbash pack delivery path.
