I absolutely love this tattoo!! I think it's beautiful, and while I think it's normal for us (who see it every day) to eventually see flaws in it, this is something we do to ourselves - I think we'll always find flaws on ourselves, it's the way many humans are wired. It's the same with our appearances and it extends to our tattoos - as they eventually become part of our appearance. We're always our own worst critics.
I think it's not much use thinking of these things as they can no longer be changed at any rate, and to me, and I'm willing to bet pretty much everyone else if not absolutely everyone else, this tattoo looks perfect. I really wouldn't worry too much, or at least try not to.
You should totally be happy and proud of this tattoo!!!
Also, always good to meet another Queen fan!
