Its looks very good. Good work, but i have to point out some things that are wrong:
first: the skin as to be more darker, and with some kind of natural pattern in the "facing up" body parts and the colour that you use on the actual model, on the parts facing down
second:, the helmet coverts all the top head, it doesn't the exposes top part on the back like you have.
Well not comparing your model with the EE made,wich is the best i ever saw outside AVP games, to bad it seams that he gave up on it
. well good work anyway!!
