Looks absolutely sweet so far. And looks kinda low poly also, which is good. It could replace the currently highest poly model.. so the average fps will be higher
You should do what all the char mappers are doing nowadays. Make a really high version, make a normal map from it, then apply the norm to the low poly.
There are a couple of changes to the character concept. Mostly in the legs.
I think it came out better then the Marine because I did a concept before hand.
So, who will rig this model because I am not. Genegineer you said you have the tools and skills, right.
