hey mann your pics not bad.. i don't take much pics of gigs (i'm more of a still-life person) but i guess some points to take note
1) try not to chop up your subjects. quite evident in your allura set. heads getting chopped off and i remember there's one pic with inch's arm only hahaha.
2) try to get a clear focus on your subjects. again the allura set a few pics with too much smoke you can't really see the person clearly.
3) capture as much emotions as you can! i liked your TFF set
probably cause josh plays with alot of emotion as well =D
4) try not to overexpose your subjects. a few pics in electrico set. your balance in TFF set was better.
just some general comments la. what lens/es do you use btw? flash?
