Chaos United rough concepts

I just recent had a silly idea of a comic/cartoon never-to-be about 4 lesser demons of Chaos and a crazilly loyal rogue psyker going on a quest to fetch their CSM master off a Dark Angels barge. and then the design ideas started rollin', even though I wont produce any comprehensive work like a real comic.

Still, maybe there'd be a series of pictures, and I aimed to try out a simpler, cleaner cartoony style that would look ok and easy to say, animate. So here's some rough design concepts.

C&C plz, wanna hear some input about this.
