*Cringes* x] There's some good and some... not so good in there.
I've not done an oriental style before. Closest I've come to it is probably
this. I've always been interested in designing tattoos, though. I do mostly digital art, sketches or full coloured pics. And lots of texturing. But in tattoos I have very little experience. For such a large and visible area as the back, it's probably best you find a professional to do a real decent job of it.
Oh, and you have to take a picture when you finally get it!
