About the texture: I'm not sure what it is about it that puts the image off. Perhaps it is too uniform... even folks that spend a majority of their time outside have tonal variations under their arms and at the groin, at their elbows, and sometimes even at the hands and chest. Not everyone is the same, however, so if you like that particular texture, stick with it! My comment about the hair stems from the way it is not reacting to gravity. Some of the hair at the back of his head, and definitely his bangs need to droop towards the floor (even if ever-so-slightly). Of course, these are merely suggestions... take what you want and leave the rest behind. What you have is still really good. I look forward to seeing any final render you choose to show.
