This one is a bit better, I added the character to it, and changed the arm so it doesn't move so awkwardly, I also put in a bit of a lean forward, to put more emphasis on the forward kick I only added it to a few frames though, I also kept the leg in the air for a frame more so it gives a better sense of when the kick ends.
I will need to add more lean forward, and also put a bit of backward lean when his leg is in front of him to balance it. and I need to sort out his head as it very suddenly turns forward towards the end of the kick. I could also put in more in betweens to make it feel a bit smoother.
