I agree with cloning the head and also maybe the dock behind his head. I find it to distracting. Gotta watch those BGs. You could have used a touch more space left and bottom. It also could use sharpened some. If you could have done it over I feel that moving slightly to the left and putting the boys head between the dock and the building would have framed it a little better. When I take shots like this I pay more attention to the BG than the subject, not a good thing all the time. But try to train yourself and it will start being a natural part of your routine.
