Dude, that looks great!!!
one suggestion, though...you should add some really BIG blood splatters rather than just tiny ones. Like a few really long, thin splats with a circular piece that's like the size of an orange.
and maybe some blood that got rubbed on by say a dying marine or something while he was trying to...fix him up.

Maybe on the thighs where blood would end up.
just ideas, I think it would make it 'pop' out a little more. Nevertheless, nice suit!!
