From what I could see, I spy the following. You need to work on your balance. That was the first thing that jumped out at me. You seem to jump when you reach the line. Your balance is a bit poor. You actually come off of the ground with your slide foot when you reach the line. You must be muscling the ball to create that kind of reaction. From what I could see, it also looked like you come around the ball too much. This creates little leverage at the point of release.
To fix the problems, I would keep your balance arm stretched out towards your side. Create a 90 degree angle with your follow through and your balance arm. Keeping your balance arm outstretched will keep you on balance.
To solve the muscling the ball that seems to occur at the bottom of the swing, stop trying to help the ball down the lane. Push the ball towards the target and let the ball swing. Let the ball reach whatever height the ball can reach in the backswing without your help. Let the ball swing forward on it's own, without you trying to help it along.
The release, I would prefer a shot very close to the line so we could get a close up of the release. It does seem like you turn your hand too early, creating little revs and little leverage.
A Storm is coming.
