The thing that I immediately notice is that she is standing in the middle of the frame. I think the single biggest thing you could do to improve this shot is to crop it so that she is on the left third. That would leave some background for context, but would help eliminate the static-ness that goes with a centered composition, typically.
Technically, I love the clarity in this. The detail are awesome, and I'm thinking you nailed the exposure on it. Some of the whites where the sun is hitting directly are a touch blownout, but not to the point of being distracting.
Overall, it is a good shot, and pleasing to look at. While I do think you met the challenge, I also think that if you could have captured her (obvious) intensity during some action of the game, you would have scored even higher. Good work on your first entry. I look forward to seeing more of your entries.
Great job! Wonderful exposure on the face. If you used a fill flash, there is no evidence of it, other than a great looking image. The background is perfectly blurred, throwing the attention to the athlete. (10)
Despite being a nice photograph, this entry does not fall within the parameters of this weeks challenge (action). That being said, I must judge this photograph accordingly. :-(
