Football game

I'm hoping to get some C&C here....Please be honest and give me ideas on how I could have done these shots better...they were in the evening...sunset and later.
Thanks guys!
Mike

1) In action shots tighter usually = better. In number 1 I'd crop out the hand at the bottom (or clone so as not to lose the feet of the others) as well as cut out the top. Interesting chase shot.
2) Same thing with helmet at the bottom. And I hate myself for saying this but fix your horizon. Also possible crop everything to the left of #97 at the top. also, get lower if you can, it'll add some depth to the shot.
3) faster shutter speed - look to get a lower angle as well to give yourself a more even background.
4) too dark for me, and I'd rather see #1 by himself taking up the whole frame - it would be a more powerful image I think.

On the whole I'd take a look at the WB, the colors seem unnatural to me.
