A good start, but you also need to think about the background as well as the foreground.
#2 has a post growing right out the top of her head, and she's impaled on it too !

The people in the background are distracting, you could move to your right and put them out of the background, and remove the pole from her head too.

I see you're using 70mm f/5.6, I would want to use longer lens and get further back.
If you have a f/2.8 or even faster lens then you could use the widest aperture to blur the background.


Did you notice we have a sports forum too ?
I think more of our sports shooters would comment there, plus others have shot athletics and you'll find some long jump examples there.
