not sure what a tattoo artist would do with a photoshop document.
The best tattoo artist make their living by being able to free hand and draw.
If you were serious about the tattoo, I'd suggest you contact your artist, and have him draw up a design.
even if you give him a design, he is still going to have to re-draw it himself.
and there is nothing like having a tattoo someone else has...sweet!
So if you meet me Have some courtesy, Have some sympathy, and some taste
Use all your well-learned politesse, Or I'll lay your soul to waste
