I like the vogue tattoo idea, too. Take pictures if you ever have the chance to do it!
I know that I want an Ayu tattoo, but I'm not sure where or what I would want. I really, really like Ayu's back tattoo with the heart and one wing, but I'm sure a lot of people will think it's unoriginal. I'm studying Japanese at school so I'm thinking that I will get the original Japanese lyrics of (perhaps) fated or Last angel tattooed somewhere.
