Lookin cool dude! Just a few lil things that might help ya on the way! When ya have a character standing, try not to squash them to make them look animated, it looks a bit unnatural, Also try slowin down some of the movements in there, You could get some more impact on those sword swings to really show a nice solid slash attack! Though overall it ain't too bad man! Liking a lot of the moves ya got goin on there~
Adding to what Kirby said, there's no real reason for the fade and long wait from 0:05 to 0:08 before Mali appears. Just have him already walking in and hitting the dude when he flies into frame. Try working on physics too. The bounce off the ground at 0:12 was a little weird with the way he just splatted on the surface for 3 extra frames or so. Either have him bounce up immediately or get rid of the bounce entirely. Nice combos and speed effects! Keep practicing~
