Looks too orange to me. Personally, if I was shooting this (well, if I was shooting this, I'd have some explaining to do about what I was doing with your wife and she was nude...), I'd focus on her eyelashes and go B&W and high key. But that's just my vision of the possibilities here. I've attached an example below to show what I mean.
Lew did a great example of what I was going to effectively recommend: go to the RAW file and try a couple of different versions of the photo by altering the WB. Then look at them. See which one either looks more natural OR achieves the effect you want to achieve. And then you start to learn "okay, when I shoot with this lighting I need this setting." You can even start to play with custom settings.
