I was commissioned to draw a Thor piece a while back. (Look! It's a Thor: The Dark World tie-in!) The interesting thing is that I was told that this would be turned into a tattoo as well.
That just blows my mind. I've famously said that I would never get a tattoo* since I'd feel obligated to get some of my own artwork, and I can't stand anything I've drawn that's over six months old. That's part of the nature of being an artist if you're doing it right, though.You should keep improving.
So when someone says they want to affix some of my art to their person forever, that's amazing. The art I did was flipped to make it work better on the designated location, but i's definitely my art. Incredible!
(* The only exception being if Paul Storrie and I ever become hunters and need an anti-possession tattoo.)
