Thanks Vipershark; I haven't done anything drastic just yet, but I added some leg movement, tweaked the timing to give more emphasis, and twisted the main body a little while slashing/afterwards. I also got rid of the smoke because it was getting in the way of properly animating it. In-game the smoke would be generated separately anyway so it wasn't really needed here.
I think it looks a bit better.
Edit: One of the frames had a pixel off. Fixed.
Edit2: Found another one.
