Lovely series. For the first shot, have her move her knees about 5-10 degrees to the right. That does several things. First, most women's legs--shot straight on--look very thin, like sticks. Don't have the shins facing the camera straight on and you see more of the calves, more form. Also, it shows more of the thigh (and hers' are lovely).
All of the shots are very good. She looks lovely, the outfits work well.
