Excellent, I love these kinds of pictures and she suits the landscape.
The only one that gives the game away is the third picture. Her feet should be buried a little in the sand, easily done by rubbing out the soles of her feet and perhaps putting a shadow or such around the foot. And of course she needs a shadow of sorts, with something like 50% opacity. Of course assuming you have a paint program to do it, FA doesn't have this kind of editing.
But otherwise lovely shots and enjoyed viewing them. And she is a beauty. That hair really suits her!
