It kinda sucks that you've gotta cover up half of the face with the mask, but besides Mike's suggestion I dunno what you could do to fix it. A see-through material, maybe

Anyway, great work on the cloth once again. I'd love to see a wire of this thing. It's refreshing to see someone still rocking on polymodeling instead of resorting to sculpting on a difficult model.
Also, there's a grey bit on his left arm at the forearm, I'm not sure what it is.
