Or even a touch of fill flash... so that you could keep the exposures on the windows correct.....
Personally (and I stress this is just an opinion), I would prefer to see less detail through the windows, it is just distracting. Blowing out windows is a good alternative to using a shallow depth of field to eliminate distracting backgrounds, plus it lets you keep the subject sharper and in full focus by stopping down a little. I do agree though a small amount of fill flash focused on the dark side of her face, would help the image overrall.
