Some real good photography - you've captured the essence of live music photography (capturing the mood & movement). I love the first shot of the city skyline, straighten that horizon and it'll make a great wallpaper.
I disagree with Felix, I like the composition. Lots of lines to lead your eyes around the image. I do find the use of small light at the bottom interesting.
The M16 is a beast when used correctly - it's good silenced, especially on S&D. I can't wait to play Barebones after I finish work experience on Friday, should be fun!
