Sketchy animation

I'm a sucker for emo-ish animations. It just gives me a certain kind of feeling. An excitement? Maybe, but more of an obsession type of intrigue. Angst is perfect, especially with its sketchy style.

I noticed in this that ambience sfx + voice = good, although the voices are just grunts and screams.
I wonder if a depressing music is added in, would it be better?
It's definitely an inspiration for my next creation
