I think that his body is too thin at his six-pack, it's almost looking girly. Notice how Chris' example isn't thin at that point.

also one thing you need to consider is sprite depth. For example, when making that pose, people will hunch their back a little, lunging his arms and head forward. This makes his stomach behind them, so the chest will cast a shadow on his stomach (that is, his stomach will be darker due to beng behind the man's own body). His legs look better, but arch them a little more and make it so it looks like he's taking a step forward (one leg is in front of another). You will have to redraw some of his legs and the back one needs to be shaded a little more stronger due to being behind.
