OOh, very nice work on the leather, the textures look great! The materials feel really alive.
The metal bits feel a bit like painted porcelain to me for some reason, I think the reflections might be too strong.
There is a stolen angle (Not sure if that's the proper name for it) where the jaw line continues with the neck of the suit very closely. It makes that part look a bit disjointed to me.
The edges are rather sharp at the outlines of the figure (especially at the hair, which look too uniformly flat)
Sorry if it comes down as too negative, these are mostly nitpicks, and only my opinion. Your work is really inspiring.
