He is utterly grotesque, I love him. What's he made of?
That's a good compliment!.
For the face portion, alumnium foil core covered with masking tape and polymer clay (fimo classic mixed with pure glyrecrin, until it got to a chewing gum consistency so it could be threaded, made into blobs or also sheets) sculpted with dental tools and brushes, painted in layers with genesis heatset oils. The eyes are polished 4mm onyx beads with calcareous inclusions (white spots).
The body has ragged skin that's done with epoxy putty.
