Expressions Dance Team, Chico State

First time covering dance, second time covering performing arts. I found it to be very challenging, the lighting was constantly changing and the action very fast. These were taken with a 40D, 70-200 f/2.8L, at 3200 ISO f/2.8 and shutter changing between 160 and 320 or so. Anyways let me know what you think and how i could improve. C & C always welcomed!!

I like 1 and 4. On number 5 the leg intruding into the frame on the lower left hand side could probably be burned a bit so it wasn't so bright, or even cloned out of the frame completely. If it wasn't there I think 4 would be a stunner. 5 is nice capture although the arm in front of the face is unfortunate.

First and last are very nice.
Agree with the leg on #4. In #2 it's a pity you cut off a hand...
