For what it's worth, I would have gotten her into an outfit that complimented her complexion better and kept the photos in color simply because of the color of her eyes.
The one on the horse is by far the best, imo. Love the blend into the mist effect that you got.
On the others: I love natural light catchlights in eyes and pinpoint flash bothers me... this is very obvious in the first one and it also just looks "flashy".... She has such beautiful eyes, I wish you could have positioned her to have "caught" some light in them.
