This piece is part of the artist collaboration "Folklore Bestiary" hosted by the Hellfire Sculpting Club.
The Topic was to create a bust based on a folklore creature based on the birth country. I picked the Kielkropf, which is a changeling and is described as deformed child based on hellish or demonic influences.

Feel free to take a look at the other folklore busts too!
