have u noticed how her face seems to change in every shoot? the first one she did - the one every saw at once - is pretty, but then later on, eg the pornfidelity shoot, shes so frigging amazing! that said, i liked the sunglasses.
I think the way she has her hair makes a big difference in her appearance, and in most of the links she as it in a different style each time. She looks the best when it's down.
