Yikes! This thing is huge! I don't think I would have liked to meet it when it was alive, it's like it's still teeming with hatred. I guess not everything gets to rest in peace. It's really clean though. Whatever owns this seems to like it very much. Perhaps it is a trophy of some sort from beating this guy in battle. There are some scales and pieces of fur next to it. I wonder what they are from.
I was just thinking some maned Cerberus character but then I saw those beautiful snakes in the bottom left and I'm wondering if you could incorporate that too, somehow.
Ah, didn't see the dungeon closed, my apologies!
