I'll give you my two cents.
Work on your movements. There a little all over the place, and quite random.
Don't grab as much. Try to grab as little as possible. If you need to grab, do so. If you can figure out a way to do it so that it's unnecessary, bueno.
A boom always looks nice, but it's not necessarily required. If you can fit one in somewhere, all the better.
There are some odd hits you do that don't make a lot of sense. There are spots where you could kick, but you do a punch that would be weaker where the kick would be stronger, and vice versa.
You're on your way, but you still have a ways to go.
