The moment is quite interesting - the stillness of the number 13 against her opponents works well. There are a number of things one would like to see to improve n the dynamic and power of the moment though: getting the instant of shutter release right is one thing, but there are others. The angle of shooting is strange - if you could get lower you'd get more impact, and certainly more emphasis of the relative height of the girls and the effort involved in the jumps. The line of the crash mats would be less intrusive also, and you'd perhaps have the added dramam of shooting into the lights, with the great geometric effects to be gained there. Some contrast work in post-processing would also be nice - either to make those colours pop a touch more, or to remove them, and use black and white to get into the physicality of the sport.
Only thing that would have made this picture neater is not having that arm blurred, but then again, its hard to do while people are moving! So I'm gonna say that's a neat shot!

P.S. I JUST thought while I was giving you a score that it was neat how clear the #13 is!
She reminds me of a girl I knew in school. Short, but a really dogged, quick, aggressive, and hence excellent basketball player. :) Good capture -- just a tiny titch faster on the shutter speed would have been even better, imho, but I know that dealing with existing lighing in school gyms is not easy.
