That looks amazing. Simply great. no crits.
There is one thing though. I'm doing a big efford to like the colors you picked, but they're not realy working imho. There's to much colors i think. Yellow, red, and then his blue head... The texture work itself is awsome. If you look at the pieces separatly, they look great. The gun and armor, nice damage there. The head looks nice to, saw that in the wip thread. Took the liberty to make a
greyscale version of your first image, and imo it looks twice as cool...
But like Snipergen already pointed out, colors are a personal thing, so don't be to hart broken. What you have there looks like a first class unreal character... very nice job
