I like how he's got a purple hand. The reflections and stuff in the glass are happy, they go over his face but not so much that you can't see his expression- which is priceless, btw. "OMG LIGHTNING POWERS!" Indeed.
...Aren't rules about taking pictures of other people's children? Or is it one of those 'public place' loopholes?
The size of the hand in relation to the face is great, for me that is my favourite part of the photograph as it drives home the premise behind the capture! Did you ever have a chance to see ~roy204 's shots like this?
