Not bad for a first dm kick:
Flaws: It didn't look particularly nice, obviously you're not going to have to worry about that too much now as you're new but look at my improvements, if you practice them you will get much better.
Ways to Improve: Make it look more fluid by relaxing the joins you aren't usding. Either that or use more joints to make your strikes hit harder, experiment with moving the hips and glutes to improve the kicking power.
