I am glad you like the artwork. The angel represents many things in my life and the images have many representations. I drew the legs bound but still unraveling (represents journey to be freed of many things) the upside down cross is part of the anatomy, I know black and white isn't always as clear as colored.
The cross on her arm represents a reminder of religions and the betrayal, with the beliefs of man intertwined with the ritual of religion; how can it not be corrupted?
The link above is the picture that looks like Moe in the face.
