The white and yellow take too much away from it, also a little too bright on his face. Overall I like it and think it was executed very well.
I agree completely, also I really like the texture on the background, nice work man . I haven't seen to many MGS sigs, and this is a pretty damn good one ^_^.
I like the texture in the back (although used alot ) I don't like the "tech" text though. It's a bit to bold.
