Another pencil work

At the risk of sounding redundant, I just want to say that your style is very realistic and attractive. It kind of reminds me of video game/movie concept art, or a graphic novel...I can't describe it well.

On anatomy, I only see two things to be fixed. His ab muscles seem to be too far up, or at least his upper abs aren't small enough. (I've heard the term "six-pack," but I know that there are more sections of muscles surrounding the six.) His eyes might be a bit too long, I'm not quite sure but they might be too close to the edges of his face.

On the plus side, the overall composition and skill is great. The insolent/sarcastic expression on his face completely goes with his pose. The wrinkles in his shirt and the folds in the collar, plus his hair is nicely styled.

Overall, I bet this would be a very cool image if it was completed and filled out. Keep it up!
