These are great shots especially the first i love the way you composed it with the lights on the right and the last which is really nice and focused. Trust me i know how hard it is to shoot a concert/gig/band, i had an opportunity a couple of months ago to do one and the DPS forums helped tremendously. I also did a ton of editing in PS to get the exposure and colors just right

These look really great and i hope you're very proud of yourself! Kimi
