I think you are too young, it is illegal for anyone to ink you, and that your choice of tattoo is quite cute – very predictable, unoriginal, in a ‘fashionable’ spot, and might as well be stamped ‘circa 07/08’. You did ask.

If you are asking, it probably isn’t perfect for you, so, no, you probably shouldn’t.
When you see the perfect tattoo, you will have no doubts, and will feel no need to ask anyone Else’s opinion. You will just ‘know’. =)
