I like the concept
but i think the design of that white torso bit is overly and unnecessarily complicated. I dunno what it is, but a lot of people seem to think that the more 'realistic' armor is the more purposeless aspects it needs to have. like the Dark Knight Batman suit. Or Master Chief's armor. or the New G.I. Joe suits. The textures were handled a bit strangely.
whatever the case, it's not a terrible drawing.
