Ok, so I've been to 2 concerts and taken over 400 pictures and I've only got a handful that I like. The main problem I think is my camera not taking a quality photo in the concert lighting, but here is one that is pretty good.
One problem I see is if you look at his right forearm, its distorted a bit.
I'm going to crop, overlay, and delete that stuff in the middle background. Other than that, I'm not sure what else to do to improve the pic.
Heres a big one if anybody wants to play with it
