Oh I've been actually thinking of them! Speculo, the Archdemon of Envy, doesn't have a body (at least not one they would show people) Instead they prefer to speak through people's reflections, whispering in their ears of all the things they could be. Speculo followers give up their faces and identities to the archdemon in exchange for their powers. I've been thinking of doing a lore dump about Speculo in the future lol, thus the concept art.

I've been thinking a bit about this recently, at least the concept of the skinsculpter. They're a former follower of Speculo (Envy) who taught them the art of skin sculpting in return for their entire identity (their name, their face, probably their memories etc). They probably bailed half way through and now trying to rebuild themselves piece by piece in exchange for their expertise. And I mean literally rebuilding themselves, they probably had to get that hair and mouth from someone.
