I’m gonna take a stab at your last photo skeeted to give an example, if that helps. I’m not a D&D person so I don’t know the names of things, but hopefully it’s a springboard anyway. (And cool artwork! I love that green glow.)

I shouldn't have tagged that one D&D. The world takes some inspiration from it, but... yeah. "Woman with carnivorous plant hair clip(?) holding a weird- looking gun with a glowing green crystal. In the shadows beyond, glowing eyes and some kind of mouth with big teeth blocking a cave opening."
