Potential Rushed
This looks like it has real potential. The special effects (Spells) and the smooth nature of your animation is delightful. The problem is, you seem to have rushed the character and setting drawings. I know there are styles with bold simplicity (It's the defining element of anime, in fact), but this is not elegant. Bold, certain lines. Conservative details. Elegant simplicity. Use these elements in conjunction with what you are trying to achieve and this could be amazing.
