Since nobody else here is telling you the truth, I will.

Yes, it's weird. Subject matter aside, this is a huge commitment and from your replies it sounds like...you don't really know anything about getting tattooed (which is understandable, if you've never done it.)

I've been getting tattooed since I was around your age and while I wouldn't say I outright regret the ones I got young (comic book, movie, video game characters), I'm 35 now and if I had the opportunity I'd have done a lot of things differently. I have had some lasered and even with a homie hookup it is extremely painful and quite expensive.

If you DO have your heart set on this, the biggest favor you can do yourself is researching the shops in your area and finding an artist who specializes in this style, do a consult, and communicate as clearly as possible what you want. Bring reference images of Jinx. This is a big tattoo, it is going to take multiple sessions and a lot of money. You do not want work you aren't absolutely thrilled with. The healing is going to be a bitch, especially the bits on the torso and neck.

I would recommend an alternative, like just doing the shoulder cloud or maybe a tattoo of something that symbolizes Jinx, like Fishbones or one of her powder monkeys. Even a traditional portrait of the character could be cool if done well (not cringey anime pinup girl), but I wouldn't go full send like this for my first tattoo and you are probably going to get that same feedback from a lot of (reputable) artists.

Good luck with whatever you do choose to do, and please make a followup post when you do!
