A little more work on the crop could have helped. Lose the person on the left, as they are headless, and the extra figure on the right. With just the boy and the person next to him (with whole head) it would have been a nice shot.

To many body parts in this photo for it to have any real impact unfortunatly. The boy does look good but the sun is blowing him out a bit on the edges.
I know the two adults aren't the subject of the photo... but it just feels really wierd that their heads are cut off. Maybe a different cropping would have helped.
This shot has such great potential - but I think you need to crop out everything but the man and the boy standing side by side - everything else is a distraction. Also the man's face is a little out of focus. Other than that this capture demonstrates you have a good eye for candid moments.
