I like the art style and the animation was great. The magic and death effects were also pretty sweet.
But I have two beefs about this:
1. 9 times. Really? About 5 would do. It soon became annoying to listen to, especially when I wanted to get to the better parts of the animation.
2. Near the end, the voices were really de-synced from the animation. Try to work on that.
Please improve these two points and your next animation could be great!
