You do have to be 18 in this country to get tattooed, with or without a parent. If you find a tattooist who will do it at 16 then he or she isn't worth spending the money on, trust me - from experiende of artists who didn't ask me for ID! you would do well to wait till you are old enough, then you can go to whatever artist you like (and there are hundreds - ranging from terrible to sublime) in many ways, a new tattoo is like a new reptile - it's a BIG commitment, you need to know what style you are looking for and find a specialist in that style, KNOW that what you are getting is going to make you happy for a LONG time. Do a lot of research and don't just go to the nearest artist. It isn't something that everyone who does it can do it just as well as everyone else.
Having had that rant, the drawing is nice, and if you take it to the right artist then they'll be able to make it look amazing!
PS. I have a big, bright green snake on my back with great big fangs, lol, and I ain't a chav!
