Hey Oloughlinc. You have some very good pictures here. The exposures seem to be very good, and I would rather look at an image that trades blown-out highlights for a good view of the face underneath the helmet.
The first image is a great action shot. I like how you managed to frame both the offensive and defensive players facing each other down. The second image has more of an artistic quality to it, but I like how you arranged the shot so you can see the numbers on the jerseys.
I don't know what to think of the third image. It tells a good story, but I almost think that there is too much going on. The players celebrating in the background are slightly out of focus and I find that very distracting. The fourth image freezes the action very well. I like how you can see the drops of water suspended in mid-air as the defenders break up the play. What I don't like about the image is that you can't see the ball anywhere. It looks to be behind #1, who's back is to the camera. I think the image would be much better if you were on the other side of the play, where you could see the ball being batted down while the other two players make contact.
