Believe it or not, ye people of little depth. When you have tattoos, you kind of don't notice them after a while. You forget they are there, on your body, or on someone elses. So it's like finding a cookie when you see it again. Great photo. She is lovely, the set and the lighting are warm, and the ink is worth a secret smile.
She's not beautiful because of some markings on her back? It's a real tattoo, and it's reactions like this that cause the majority of her photographers to not take any photos of her back, it's really limiting.
Imagine how annoying it must be to constantly find your gaze drawn to that image when what you really want is to look at the body of your girlfriend. This tattoo makes me so sad, because it makes her upper body invisible.
