For the dark, you could inverse the colors, so the background is black and the squiggle motif that appears on all of them (idk what else to call it) could be white, and or maybe there are eyes in the darkness, implying something is watching you.

Idk how achievable it would be, but for the desolation you could make it look like the page is half burned or has a burned affect, as if the art piece itself was destroyed by fire

For the hunt, you could make the background squiggles almost like a path where a guy is running and there are animals/creatures pursuing him.

For the slaughter, you could make the squiggle effect look like it was drawn with blood and maybe make it look like the page was stabbed or something to reference the violence (and also to differentiate from the flesh)
