I know it's bad. I love corpses for maps. I want more though. More varieties.
It's macabre, don't judge, but I have ideas:
* Limbs, hands, eyes, spines, heads
* Female corpses
* Dwarf corpses
* Halfling / Gnome corpses
* Dragonborn corpses
* Monster corpses (zombies, owlbears, beholders, Illithids, goblins, orcs, gnolls, etc.)
* Corpses on spikes, corpses in traps, corpses in on ropes, corpses in stockades / stocks
Just more corpses. They bring a LOT of flavor to a map :)
