I agree that his left side looks a little bit too hot. The crops seem a bit close as well. Also, were you standing below him? I've heard before that people sometimes shoot from below to give the subject the impression of power. Which I think gives that to him here, but I also wonder if it would work better if it was taken from just little bit lower to make it seem more on purpose. The way it is now doesn't seem like it was done on purpose and more like you were just standing at the bottom of a slight hill that he was on. He has a good serious expression!
