Now, I'm no professional Artist, in fact i'd never really call myself an amateur either. But Because I'm trying to make a story in arks, I do want to make some kind of cover for each ark. My First ark, "Gaunt is the Mind" is about a Young Veteran Who through circumstances I'll not give out, has many years of service under his belt; And now tries to enter into society, though with a serious case of "PTSD" with a couple twists. What Kind of design Should I give this Arks cover? How should I portray this dark tone?
