Kudos on doing your research early. That’s the smart thing to do.

The only honest advice, guidance and constructive criticism I can give you is:

Don’t, under any circumstances, get a tattoo for your 18th birthday.
It is almost 100% certain that it will be horrible, that you will regret it, and that you will have to either have it removed or covered in a few years time.

I realize this is not what you want to hear, but I couldn’t be more honest.

No, I do honestly appreciate it. However even though I am under 18 I have 3 tattoos that were done abroad in a country that didn’t have a minimum age restriction at the time. I do not regret them, I love them very much and consider them a part of me even though they are not exactly to my taste now.
I do thank you very much for your input anyway and hope that your advice doesn’t come from unfortunate firsthand experience!
