hm... just to give some criticism: looks cool, but I don't like his legs. to me, they look way too thick, especially with those boots. i know it's all armor, but the guy still needs to be able to move!
try covering up the upper body, and just look at the legs. they look cartoonish that way, because they are so thick.
may just be the huge boots though.
or else it just looks that way because it's not yet animated.
I dunno...

good job though!
