That guy totally freaks me out!
I think it's cool lol.
I must disagree with Ratchet though xP
I think the arm's kinda good. I mean... if you take a look on someone with a robot arm I believe it would look kind of realistic.
But it would be even cooler if they'd melt together, like his skin were torn of. Like the terminator-thingy
I've tried that out... it's hard shit -.-
I like it though =)
