I would have liked to have seen her eyes in this image, she has a beautiful face. I don't want to beat the tattoo thing to death but I will add this one point. Our eyes are immediately drawn to writing/lettering, etc, or designs in the image that we would not normally expect to be there. That tattoo might as well have been a flashing neon sign for me. It was the very first thing my eyes went to and I LOVE RED HAIR (it's an Irish thing) and that is usually the first thing I look at when I see it! I suppose you could always paint it out in Photoshop, but that would be your call. Not my place, it is your image.
I do a lot of work with models and I am very selective about working with models with tattoos. One, because the kind of clients I work with have a no-tattoo policy and two, I find them very distracting. I tell the models straight up that the images for publication will be sans their tattoos. If that is unacceptable to them, well then, nice knowing ya. My philosophy is that my images are my artwork, and I don't want someone else's artwork taking away from them. I am sure Michelangelo would have been mightily pissed if someone had painted a flower on Mary's chest on his Pieta. If I cannot cover them with clothing or remove them easily with the patch tool, I say thanks but no thanks. That often pisses them off but hey, it is what it is. I am the one making the call here, not you, I am going to do what the client wants. They are the one paying me so I can pay you. Welcome to the real world kid. A lot of models today get themselves all tatted up without giving any thought to the fact that all those cutesy, faddish tattoos they spent hundreds of dollars on are forever even if one day you decide you don't like it any more and 20 years from now they will probably look fuzzy and like crap. Not to mention the fact that if they are serious about modeling, and many at least say they are, they are pretty much limiting themselves to work for biker or tattoo publications because their "body art" is not accepted in most other mainstream commercial genres.
