Not really a good photograph. Cute snapshot to remember the day at the park though. The focus seems on.
He is too center composed, there is a bit too much head space on top of him, would of been more interesting for the viewer (me) if he actually was looking at the camera, or even if you had moved slightly to your left and we could see more of his other eye and then had his head on the right side of the frame.
I dont like how he has trees coming out of the top of his head, would of been nicer if the sky was the main backdrop. I also dont like the motion/blur in his hands. It adds some distraction to the image.
Did you use your popup flash?
