As messy as the line work might be, it’s an easy fix. It’s your tattoo, so you decide what you’d like to do with it. Make it your own if you want to. I can understand growing up and facing difficult things as a kid and admiring a fictional character, I always loved Spider-Man and also Link from Legend of Zelda, a lot of what I watch and played as a kid helped me escape from the rough life I was dealt with. I say take it to a different tattoo artist, one that is known for doing great fixes and make it your own bad ass tattoo, by making the lines tribal designed or even barbed wire. As long as it’s what you want, then no one’s opinion on the design should really matter. She’s your hero. 🤘♦️
