Make every move count, don't just have them stand, make them move, the smoke could have separated into smaller particles. When he charged that last attack, he should have made motions that made the spell's force evident. I like some of the effects though, so good job with that. I'm kinda butthurt since theres no sounds.

good animation, excellent work

The moves are a bit slow. Like too much double framing and too much time between moves.
Besides that, it was fairly good.
