I admit that the animation could have been better. It's easy to tell that the skulls were just photocopied in that one scene. I still generally enjoyed this. The weirdest thing was probably how it kept showing that green heart monitor in the middle. It got a bit distracting. I guess I'd prefer it if my songs had words.
This was still pretty creative. It's great that you animated what you visualized. I do that sometimes with all the songs I review. The man is drawn pretty well. It's perfectly passable.
