The best way to go about it is go to Tattoo parlours and look at the different artists work. You will able to see what they are capable of an each ones style. Plus most tattoo artists can copy images pretty good. So if you know someone who can draw really really well you could then bring the pic to the shop and see if someone can re-create it.
