Nice angle..the problem for me is having this shot in a romm as opposed to on the courts..I appreciate this is a choice, but it pulls the whole shot out of the context you intended in my eye, and gives it a strange pretense..ie; I am good as long as I don't really play..sorry if I sound too picky, certainly your chosen angle has a nice sense of power, as does the look in the eyes..
THis would be much more effective if he were in tennis wear and on a court with a ball coming at him. As it is, it just looks like he grabbed the raquet for a quick snapshot. He has an almost angry expression. The focus is clear and the DOF is good. Just put it in a different locale (with him wearing different clothing).
