Were you using an ND filter here? Looking at it, I get a sense you had to do some processing to tone down her shadows. Still, I really like what you did with it, the color tone looks a little bluish but it works for me here.
Was she really into your photographing her, or a bit embarrassed by it? Overall, I like this look, I would have liked more down below in terms of composition and you have a gorgeous wife. If she liked doing this, we really need to see more.
