Brittany's face is like the beginning of an orgasm--beautiful.
But the body position says something completely different to me. I think the idea is for us to imagine the couple is trouncing around on the bed in a playful manner, hence the pillow and flying feathers. If I saw Brittany's ad in a magazine, I would simply see it as a couple just full-on-getting-it-on.
Christina looks awkward. Kahlen looks cute like a natural candid, but it's probably not what they were looking for. You can't even see the bra. Keenyah is selling the bra, but not "herself". I would give Michelle the same comments as Brittany. I actually think Naima looks great (she's my favorite, so I'm biased), but the lighting comment is true. I think Rebecca is in a complete shadow and therefore inconsequential. Tatiana's body looks great, if only she looked up a little more. I actually love Tiffany's photo. It's not my favorite, but I don't think it merited the criticism it received. She looks cute, sexy, endearing, and she's selling the bra.
I think it's harder to choose a picture when you're trying to remember the intent of the photo in the first place.
Also, they always put so much makeup on Michelle that she looks like a mannequin. Hmm.
