Hmmm … not sure that I like the roughed-up body. I see what you’re trying to do here, but I think the geometry is really getting buggered with this. Won’t this cause odd deformations when the model is animated?
I’d go back to the previous smooth body and add only minor tufts of hair on key ponts of the body (chest, back high on spine, and maybe leg joints).
I think we can do more with the hair on this model by painting textures rather than making the mesh complex.
I also think the legs look very fragile compared to the size of his head and body. I wouldn’t oversize the feet and legs too much, because he’ll start to look like a kitten. However, there is room for some beefing up of the legs.
