Hey, I see you're using a cover of a song from Rayman Origins (great game). The animation isn't really wrong, the movements are pretty fluid. But it's not a very entertaining video. Aside from her singing, there is no comical value, tense situation or story of any kind. Try working on that next time.

I find interesting only way of drawing and animation.
Maybe here must be some comedy or drama situation.

the character looks terrifying
