I really think her's is third best. It's stunning. Somehow it made me think of one of Frida Kahlo's self portraits, perhaps the eye contact and her arm.
I deleted my first comment, because looking at it again, I like it much better. and @ bhartle: Me too! And I wouldn't be surprised if she had other really good shots. There are times that Tyra picks a shot that I can't imagine were really a girl's best photo.
She looks amazing here. And I see the LS comparison a bit, because of the heavy brow line. I absolutely HATE the fact that most girls don't have eyebrows!!! I wanted her to win so bad... But it's hard now.
