Lilith

This is a concept for my interpretation of Lilith, the queen of Hell.
Her white mask is intended to lend her an aura of mystery, as well as represent the supposed - but obviously not effective - purity of her design as Adam's first wife in Eden.
As a demon, she became corrupt and overtly sexual, carrying out heavy sexual activity with the other demons. Her very exposed look is meant to represent that and her whip is a weapon to control the demons with which she interacts.
