Great stuff - I see you've made some awesome improvements and implemented some of my suggestions & ideas - thank you! Can I suggest more features? 1. Gradient direction. 2. Textures other than just noise with some more control over them too? That'd be great for scuff marks etc.
Might be cool to explore adding 3d & lighting (multiple light sources) as a Pro feature or something - three.js would be a good bet and would definitly take this to the next level.
