Just a few things I noticed.
You tend to get a bit of a figure eight style backswing, I do believe if you would move the ball a little more to the right on your pushaway this would be eliminated.
Also your follow through seems a little weak, I would suggest working on getting it to follow the intended path of the ball, have your arm lift straight up going in a path at your target, for example

Besides those two things you look a little off at the line, a little more knee bend a possibly a little slower on the feet could solve this.
Overall though, it doesn't look bad, its just a few minor things to work with and tweak, it takes time but you'll get there.
