Wonderful scene. Shadow is perfect - it makes the shot. Even though the sun is close to the horizon - the sky is a bit over powering. Try a graduated ND filter - it's made for scenes like this. One of my top 10 pics.
The horizon needs straightening. Also, this may be quite subjective but I would say that the mood portrayed here is not one of waiting. I can't imagine what she would be waiting for. It seems more contemplative.
