I hate setting up cloth sim
Anyway, I'd say it's doing a terrific job considering the somewhat shoddy input (skinning mishaps, clipping, simplistic textures, etc)
Definitely gets rid of the majority of "3d model feeling". The issues I can see are the drifting eye color and yellow flowers getting lost, but it's something that should get remedied with a model trained for specific character appearance.
All in all, worth exploring further with more effort put into the base 3d render.
I think we got a winner, this is real close to the style i draw in.
All it took was actually painting the textures and updating the initial shader to behave more like the way i shade. Initially it was a basic colorramp, but now it's colorramped blue shading multiplied by the painted textures.
