You will probably get a lot of different people telling you what to work on, just remember to work on one thing at a time.

Ill say that you looked out of balance at your finish. For my own game, if I am sloppy at my finish, my ball is sloppy also. Try to keep your non bowling arm steady and up more, kinda think of it like your pointing at the far left wall, that arm is out for counter balance. It should keep you more controlled and squared up.

Leg kick before the ball hit the pins was nice though...lol
