I met a girl in a club once who turned out to have a tattoo of David Duchovny on her butt. Only it wasn't a portrait; it was drawn like he was inside her butt, and he's all pressing his face up against the inside of her butt like it's a pane of glass and he's smushing himself up against the inside, trying to escape.
It was... an interesting situation. She refused to turn face-up. It was like, "YOU MUST LOOK AT DAVID DOCHOVNY IF YOU WANT TO DO THIS".
Excellent detail and colouring though.
