That's cool! The linework is very good. I'm sure it would be very hard to do that on an inner lip. How do you keep it from getting infected? Mouth is a germy place lol.
Take your tattoo for example, it's definetly not my style, but..... i have tattooed inner lips before and it is a harder tattoo to do. And I am going to rate it a 9 because of quality and nothing else.
This site is not for people to rate a 0 just because it's not their style. This site is for rating on quality and skill and originality. If you don"t like the style of a tattoo, don't rate it!
