Tattoos

Well, I am considering a half-sleeve tattoo on my right arm. I kind of know what I want, but I am a little picky. Having a little bit of an artistic side I am very particular on what I put on paper (detail wise), so am having a hard time deciding on all of the elements. I know that depending on the tattoo artist you decide to go with, you have to give them artistic license to create. But, I am not going to be very happy if ink isn't exactly what I want. I do not want to have any regrets when it comes to this!
