I don't know if this is a style complaint or not, but... You turned him into an emo kid. >.>
Okay, seriously.. hair part should be up higher, a bit less hair across the forehead, and almost none across the eyes. Shoulders need some work, they look a tad droopy and weak, and don't go with the arms, they need to be up a bit higher, with some definition in the connective muscles between shoulders and neck, a well as on the shoulders themselves. Neck might be represented as a bit to muscular.
Hope this helps, and I honestly don't mean to insult, it was just the first thing that came to mind when I saw the image.
