Too late for me to participate as well, though I did take a guess before seeing the revealed images.
1) On seeing the cropped shots, that was the first time I ever noticed her eyes.

(Maybe it's my monitor resolution, but her right eyelid looks lower.)
2) I saw her on Stern's televised radio show on E!. I got the feeling she's uneasy about disrobing, so I guessed the shot she "looks" comfortable was her clothed picture.
From the head shot, I guessed she was comfortable/clothed on the right; her head is square to the camera, whereas it's tilted down in the left (shying away from being seen).
In the revealed images, the
first second thing I noticed, below her smiley sunshines, are the back of both hands. She looks real awkward and comes off as wanting but not allowed to cover her breasts. She still looks a bit uneasy in the clothed side, but not like in the nude photo.
