I have been a horror fan for as long as i can remember.
So watching horror movies and reading horror comics helps a lot when you want to draw gore.
I suck at atmosphere though, i want heavy blacks and moody shadows but dont get them.
Edit : like this moody art by The Racks by Chikahiro
or the WW1 art i posted in that comment thread
Thats the kind of darkness i want.
I have to settle for stark contrasts.
