Epic!
There's a few problems though... The white lines on the torso goes a bit too far back and aren't as strong on certain areas (you kind of mentioned this but I'm going into detail), so it looks indistinguishable with the background to some extent, same thing with the legs or whatever, but now that I see it, it looks really cool! Couldn't tell that the zig zag was part of his head at first either (maybe add some lines on it...), but the design and style looks pretty awesome man! Great job!
