Perfect job on the muscles.

haha you're in my votes ^^

Looks great but it looks like you need to retouch the middle portion of his right arm :/

 You look pretty badass for a guy that pass probably most of his time infront of a computer 

The shading on the arms and shirt is great. I The black selout really doesn't work in some places. Watch where you use that, in the right arm > it doesn't look right, but on the pants and torso I think its fine. Good luck!
