I think you are off to a good start but I would like to see you sit or on your knees to get a better backround and eye looking more into the camera. I think 2 and 5 are the best. I would also check your WB they seem a bit blue.

So get a lower angle? See thats what Im saying. It helps to get those little tips from the "pros" as I would not of been able to tell the photog (me) was standing by those images.
I will give that a shot for sure.
As far as WB I normally shoot in auto and never really messed with the WB settings. Ill play a bit with the various settings and see how I do.
that angle really makes the players look bigger as well. Here is a shot from Pee Wee football with me shooting on my knees. With FH they look down not stop so it really will help get good faces as well.
I think you need more isolation. A good rule of thumb for sports photography is shoot tighter and crop tighter. Also there's just too much in focus. Shoot wide open so the subject is in focus and you blur the bg out.
A few other thoughts from what I have learned shooting my D300 for soccer. I would try to stay on the sun side of the action when possible. I would also recomend using Dlighting and consider EV -.3. I notice the highlights are alittle washed out, and some of the shadows are alittle dark (atleast on my monitor). Those two settings should help that. I don't use vivid as it can cause this too.
Try to shoot the lens you have at 135mm and wide open for least depth of field. Set your mode to A and let your shutter speed adjust for the lighting. I then adjust my ISO to keep shutter speed above about 1/1000.
Ro...Agree with what others have said here.....Gotta ask where you are from and where were these shot. The girls wearing the "Nanticoke" uni's are about 5 miles from me. Small world.
