Tattoos are not something that you just get on a whim. A lot of times they are well thought-out and for a lot of us, they have powerful meanings behind them. So would you let just anyone tattoo you? How about someone with a prosthetic arm that was designed for tattooing? I'm all about the saying "A picture speaks a thousand words," and if this guy's artwork looks like good quality work and his past clients are happy -- hey, why not?
