Well....I like your photo. I suppose I could provide a little cc since you ask, and I feel I learn more from CC other folks photos than looking at my own:
I'm not sure about a few elements. I suppose I don't find the photo extremely interesting, since he doesn't seem to extremely interested in his playing! As a matter of fact, I don't think he's interesting really at all. Not that all photos need "energy", but this guy seems to lack even a small degree of energy that I would like to see. Or any emotion really. He seems to be bored, looking at, what I assume, is the conductor. But it's really the shoulder (?) or whatever it is in the lower right corner that is a distraction. Thanks for letting me critique!
