I think a different crop would do this photo great justice. YTou already have a good image and that is 90%. Now crop it tighter with the boy on the far left. Also maybe darken it a little. Either way it is a very good image.
Agree with the others commenters: you get a wonderful b/w and the object if too centered, not dynamic.
But the expresion of the kid is outstanding and the DOF very good.
This is prety good. Nice tonal range, cute kid...sad too. The only thing that bothers me is that he is smack dab in the middle of the frame. This makes the composition very uninteresting. Maybe zoomed in closer?
