I would love to see a scenematic drawing of an Unraveler killing a paladin. Just imagine...
Hes on the ground, digging his fingers into the ground (stone), being dragging away by this thing with a giant bloody claw.
Or make an manga-style drawing of the wanderer giving the sad puppy-dog face and tugging at the lunchlady's shirt asking (more, please).... with hints of hell seaping in from behind him.
See if you can do a tribal design that incorporates the diablo logo and/or other diablo references. A couple npcs have symbols for example...
Draw a bunch of nerds cosplaying a fight with diablo.
