One of the main characters in Adventure Time Marceline is a half-demon / half-human and vampire who, I heard, is over 1000 years old.

This one was roughed in Monster Clay over a metal armature, then moulded and cast in wax (Tim Bruckner’s recipe slightly modified to fit my needs). The figure was detailed in wax and moulded again, to finally be cast in resin. My daughter loved it!
