These are decent pics, but something seems up with the focus. It would be easier to critique if just one was posted, so keep that in mind next time For the first one I think it would be better if the action was completely stopped rather than blurred a bit, and have the DOF different where the people in the background are blurry. For the second it seems that there is too much to look at. At tight shot of one of the players on the ground may have been better. I like the last one best out of the three, but as far as suggestions on it goes...one girl is in focus but the other two aren't, but they are still sharp enough to be seen which is awkward. I would suggest to next time fill the frame with just the one cheerleader, or to have all three in focus and then the pic would be better. Hopefully that helps a bit! Looks to me like you've got the right idea goin on, now it's the execution that's important
