Great timing- the hands of both father and son make the shot. I think the light cooperated, allowing you to frame the father in the foreground and intentionally dwarf his son. The father's reflection works, creating a pleasing "V," as well as a virtual spectator.
I'm not sure what I think about the woman top right. I assume you're trying add context here, but I find her a bit disctracting, as she's walking away from the subject, taking my eye with her.
