First, congratulations on having someone to model for you. That is the biggest hurdle!
I concur with BC. There is room for improvement. But, I also remember that beauty is in the eye of the customer, so all our advice is measured with that in mind.
Without repeating what was said, I do notice that her hair looks like it is being blown back so it looks active. Great for the beach, but not for a bed & glamour shot (IMO). The first shot has a lot of white. I think that I would try some post processing to blur out most of it to remove the detail.
In the second one, I agree that it is pretty blown out (maybe that is what you are looking for).
