Dark animation references

I want to turn the story into a dark type of animation so below are some videos of the kind of darkness I would like to do.

Hounds of Flesh (Pica Tower Series) by Marc Craste and Studio AKA


The Pearce Sisters by Aardman Animations and directed by Luis Cook

AtomFilms.com: Funny Videos Funny Cartoons Comedy Central

Insight by Salvador Simo
I really like the style of animation. How the characters and cats look.


Live Life by Jonathan Pasternak
I like the titles for this and I think it would really suit my story so I may use that.


Space Alone by Ilias Sounas
I love the music. character design and the sort of static over the top.
