Something missing

I really like this shot, but the more I look at it the more something seems wrong. What do you guys think.
As it came out of the camera. What PP do you suggest

If you shot Raw, start with adjusting the white balance, then work on the exposure (fill light).

Q

My first reaction is that you do not have a clear view of their faces. One is out of focus; the other is turned away from the camera. Technically, it looks like the light was fluorescent. I'm guessing that the wall in the background was gray. That's where I would try putting my gray eye-dropper in balancing the color. Also check the levels. You might not be using the full tonal range.

Thanks, the pic was shot as jpeg, I'm starting to use RAW alot more now.. I shall work on the white balance, as I recall the wall was beige, but the tire on the wheelchair looks like it may be grey. I will try both ways. Definately was flourescent.
I understand about the faces.Its tough to get depth of field inside. The Xti only goes to iso 1600, I don't like going there so i stay at 800. Next time I will try to get one face in a fuller view and eliminate the second person.
I will spend some time working on tonal range, I understand the concept but not quite sure how to get there. I will do some PP and repost the pic, probably tomorrow.
Thanks

Until I read your post detail the only thing I noticed is that there is no ball in the shot.

you're right, there is no ball. That is something I am working on. I often go to wheelchair basketball games, I have been asked to take pic's and have a slideshow at that evening's supper. The only request is that I have a pic of every single player, because everyone likes seeing themselves.
Sometimes there is a ball in the pic sometimes not.

Anyway I couldn't wait to try some pp on the photo, ( i guess I will be a little late for tonights plans) I think this looks a little better.
But I don't think this will ever be a great pic, because of the composition.

There's a few more ball pics in my flickr stream. This just seemed to be a good of example of some my shots. I need to know what I am doing wrong. All of the ball players are always happy with my pic's and pat me on the back lots. But I am never happy with them, i know I can do better I just need a little help and it seems there are lots of people here willing to do that. For which I am truly grateful.

I did exactly as Joedlh suggested I used the back wall for white balance and increased tonal range ( I didn't know how to do that 30 minutes ago) by using a histogram and level adjust.
Q-man said "then work on the exposure (fill light)." not sure how to do that. I will work on that.

Ah, if you need shots of every player, then shoot the warm ups too.

If you want to get their faces, get under the basket, get low, and fire away.

How about, compositionally, giving the player more room. I think the tight crop is what I am finding bothersome.

Yes, sometimes I shoot the warmups, Prefer to get shots are playing while they are playing. I'll will try to get under the basket. I always try to stay well out of the play of the game. Nearly always, there is not enough room and the end of the court and it sucks getting hit by a chair.

ejay79. This pic I can't change, But i will try not cropping so tight. I do like tight crops so I often do that. I'll try something new next time.

Thanks for your help everyone. It's helped. Can't wait to get out and shoot ball pic's. But unfortunately the season has ended.
I think I will shoot in RAW all the time now. It opens up more possibilities when you do get a decent shot. External hard drives are getting cheaper and bigger all the time.
