Sounds like your friends had a good experience, that's really cool. It's so important to take the time to find a good artist, and one that specializes in the style you're looking for. (After all, it's going to be with you for a while! ?_?)
I have two so far, and I'm getting two more in about a month... The first one I got is three X's, one on each shoulder and one on my back, between my shoulder blades (I'm straightedge). The second is a large script piece on my belly, says BELOVED surrounded by art nouveau decorative pieces. (Styled after Sailor Jerry's stuff.)
The next two pieces I'm getting are both on my back... On the top I'm working outward from the X, putting a half-folded old school shaving razor behind it, stretching from shoulder to shoulder, wrapped in ivy. The second one (oh boy, oh boy!) is a reproduction of Hokusai's masterpiece watercolor, The Great Wave at Kanawaga. I'm so fired up... ?_? My artist is the one guy in my state (and I've been to most of 'em) that I would trust with that piece, because he's as much into Japanese watercolor as I am!
