What I want is a custom biomechanical tattoo (yes before you ask it would have a menaing to me). When I can afford it (could be a while.. and can travel) not sure the local tattoo parlours can do the detail I want. I know what I want and have a general design idea but putting it together in a final design I can't do I'm not artistic or vey imaginative at all. Now to have a custom piece designed how long does that take? Day’s weeks? How long would it take to have a half sleeve and shoulder blade and on the chest about the same area as the shoulder blade done? could it be done in one session.?
