Good use of shallow depth of field. Exposure is right. The kid is certainly cute. But the picture feels like something is missing ... like maybe he needs to be put into context. For example, if this is a hockey stick, then perhaps putting him at the ice rink would finish the picture. Instead, it looks like a living room or something behind him... Good luck in the challenge.
The little fella looks a little shocked maybe you shouldn't have used such a bright flash! ;-) Would have gone with a little more contrast myself, but still a great shot for the family album!
5. It's a great pic and a great moment. Unfortunately, on-board camera flash has a way of flattening these pics and pulling away from the final product. It would be nice to see a non-flash version.
