I agree with other comments about the guy on the right being too fuzzy (sorry I'm not really into metal bands). Since the guy is sort of fuzzy maybe just cropping him out and using the bass guitarist as your primary subject would make a great photo in and of itself.
I love it. If this band was really famous, like Rolling Stones famous, this would be a world famous photo. I'll add here that I like how you carry a recognizable style through your shots. Especially impressing considering it's mostly concert photography - in impossibly hard genre. Anyways... Keep up the good work!
