Unimpressive
As a second work, it is understandable that you're still working on technique, so the lackluster animation style was acceptable. However, I found this to be nothing more than yet another "Insane Murderess" tale, simply death for the sake of death. There was nothing to keep me engaged, and the song didn't manipulate my emotions to feel anything for these characters. The gimick with the breath was nicely animated, but uncreative. Plus, the whole thing was too short. Work on developing a plot and characters, and the animation will come in time. Good luck on your next piece.
