What exactly do you feel that you need to work on?
There are a couple minor issues, one of which is inconsistency. Hard to pinpoint one thing to work on if you're not repeating it. Is it a one time issue, or does it keep sneaking in?
I noticed a couple of times you seem to over-rotate and end up facing third base. This may be from your glove hand ending up on your right hip instead of up toward the shoulder (indicating that you may be swinging your arm toward the glove side) and you may want to work on bringing that glove hand straight into the shoulder, but I don't think you have a lot of reason to mess around with what you've got until you are throwing for your coach.
My advice is to get Tuff Cuff and do those workouts, and throw with someone who knows your game, or even better, your coach(s). Stay loose, stay hungry, and get good grades!
