Mm... The only thing I can comment on here is the lighting is the light shading looks a bit too.. uhhh.. in between for lighting. What I mean by this, is the reflections on the suit and skin make them look like rubber, as they are slightly brighter whites than skin or cloth would reflect, but yet, and the skin highlights are also a bit too dark to be from moisture on the skin. Possibly it would match up if there was a light layer of some kind of oil.

But anyway, that's just nitpicking the shading. I usually do mine by hand (cause the program doesn't have auto-shading) and estimate where everything goes on a separate layer. I then try a smear brush to muddle the straight edges created by the brushes, so that when they are put down they appear to be more progressive instead of sudden layers.
