Something I would consider is getting a vid with you playing a few different lines. If you have multiple releases ect show that as well.
I would set the cam up on the right side of the approach for some shots, along with some shots of you from the side throwing the ball to show your full approach. Then I would work heavily on spares, and making sure your an excellent spare shooter. Those things will go along way in scores, and maybe showing your a complete package of a bowler for different schools that may be interested.
Hope it helps and good luck.
Be good, or be good at it.
