Ha, nice video. What did you edit with? Looks like it was a simple editor. The more you pay for video editing software the more you can do. Also, check the frame rate on your camera. If you can film in a faster fram rate, do it. It will make the slow motion stuff look so much better.
As for your form, I think this is one of the best videos I have seen on here in a while that asked for feed back. You form actually reminds me of Will Schusterick.
That being said, if you are looking to improve, I would suggest a couple more videos. First, the infamous Dan Beato video. It appears as though you may actually have a tad bit of deceleration right as you realease the disc.
Also, I would double check your grip. Dave Feldberg does a great job of describing a good grip that will help transfer more power from your body to the disc.
Keep having fun.
