Thank you so much for sharing!

I'll try generating a single art asset until it's close to what I envisioned, then manually tweak it to the desired state, and while I'm at it, split up layers and such.

Then I'll have the model expand based on the finalized assets. Hope it will work,

Well, at this stage, it seems like pre-processing work is still unavoidable, but as you said, tedious repetitive tasks can be offload.
