Well, I am not usually one to make such comments because I can't paint much better than a 6-year-old. But, if "forced" to comment, I would say, over all, it has sort of a "flat" feeling to it. It doesn't possess enough "depth". Maybe someone with more experience and talent than me could offer some tips but all I can think of is the following: Looks like some shadows are missing on the belt (from cloth overhang). The same goes for the feet and ankles (and the character's right wrist. (but maybe you only want comments on the cloth itself) Looks like there are shadows missing on the arms where the brown material runs into the white material. Your shadows, overall, look like they could be a bit darker. It seems to me, when painting, it's OK to exaggerate a bit to make up for things being two-dimensional. I would make the definition more obvious where the robe overlaps. It looks OK above the belt but it lost its "flap" below the belt. Otherwise, your folds look fine to me. I wish I could do as good a job as you have done! Hope you remembered to make your image big. Cheers!
