Hey Chris,
These look better to me. The action looks good, you've isolated the ball carrier well, and you've captured their faces, and eyes in some of them.
These girls play hard and without helmets too..., their hair flying around is a nice touch as well..
The tighter crops look better! I also like the colors and I think the exposure looks good too. They don't look too noisy either.
Watch the horizon in the 5th one. Some of the faces still look a little soft to me, especially the 5th one, which looks slightly back focused or missed focal point of ball carrier. The focus point looks to be on the girl to the left of the ball carrier, as opposed to the blonde haired girl with the black headband.
I don't know what your shutter speed, ISO or apertures were? Perhaps a faster shutter speed may be necessary, butI like the narrower DOF in #5 and #6,
It looks like you were standing in some of these, so try and shoot a little lower if possible, perhaps down on one knee, as it will provide a more pleasing background and better impact of the runner.
Nice set, thanks for sharing and keep up the good work!
Rich
