this is a good simple shot.. i am assuming you are using Adobe PS to edit out the background for which you get some good credit. You should however make use of less flash. I don't know how it works for your camera.. I sometimes disable the flash in my coolpix 4500, and use slow shutter speed.. the general expression and capture of the mood is well done..
Wow! Put a striped shirt on him, and it's TOUCHDOWN! Really nice expression, great capture. Is he lying down on a pad, accounting for the shadows behind his hands?
