Hi!
I like the movements and the animation in general, looks really nice!
My only problem is the background, its too simplistic in my opinion, other than that, great job!

Cheers!

The animation itself looks fantastic in my opinion, very detailed movements.
For a better look, I would probably just improve the textures a bit ( making grass more complex, adding different lighting in different places etc. ) and also probably add like some sort of glow or blood on those attacks.

Other than that, this seemed very fine ^_^

practice is how one gets better :)
