Im covered in tatts from head to foot, lots of home done jobbies but mainly prof ones, with me working all over the country i have had them done by a lot of different tattoo artist and the best i have come across is a guy called Dr Graham (grangetown, cardiff) loads of jap/chinesse art.
The last one i got about 6 months ago was a galleon and two carp on the bottom of my back (only bit of space left nearly), these were done at a small studio in Whitby by Shane Somers, he has a lot of jap art and he was one of the better artists i have use.
Its like everything else, you pay for what u get, and if its to be there for life, its go to be good.
