3D steampunk whale in Three.js comparison

Someone gave Opus 5.5 and Sonnet 5.5 the same structured workflow to build a 3D steampunk whale in Blender and run it in Three.js. Opus: 2.5M output tokens, ~$156 Sonnet: 1.68M output tokens, ~$109 Sonnet is impressive for the price, but Opus produced the richer model and better animation.
