Aren't most artists pretty reluctant to tattoo faces anyway?
I heard a conversation when I got one of my tattoos to the effect that the artists were generally reluctant to do faces and would only do them if the person already was significantly tattooed. I guess that wasn't the case for the guy who did this tattoo, but I'd imagine that the process wasn't:
"I'm 18, put some freakin' stars on my face."
"Ok, cool, let's do it. I don't need ID or to quote you a fee or sketch anything on your skin for you to look at or nothin', I'm just going to freehand some stars."
