What does an artist look like?

I've posed this question toward the reader for one sole reason. I've been told on numerous occasions that I "look like an artist". So what exactly does an artist look like? At first I thought it was the tattoos. Yea, that must be it...tattoos equal artist. That has to be it. But no, that can not be it. People say this to me even when I am covered up. So what is it? And why is it that people can spot that I am an artist right away but struggle to identify my race? I find this phenomenon very amusing.
