Let's give the rest a quick go over:
1. Too far away, crop much tighter, horizon off, background is not the best although a very tight crop should improve it.
2. Ball is very distracting as it pulls the eye away from the player due to it being too far from the player. Shadows need bumping...
3. Two concerns, first no ball but also look at the hand. Not something to give to the mom, IMO. BTW, horizon off a tad.
4. As I indicated earlier, the best of the lot but bump up the shadows (too dark).
Keep shooting, it gets better!
