I like the animation! The only thing that really stuck out to me with it was the fact that his hands are both in the same place on the hilt when he swings his sword. Hands are usually as far apart as they can get when holding a sword hilt (more control that way, but I digress).
Nice work. I think the knees should come higher up when he's walking, though.
Good cycle, good colors! Amazing.
I am sorry, white background removed :)
Remove the white background, please.
