I agree about the model's look - BUT she could be seen as a wolf in sheeps' clothing, which adds a twist to the image. Or ... I don't know how to describe it, there's the ethereal factor but adding in the Nordic (ice queen?) factor adds to the image. All is not as simple as it seems. Folk tales tell us that human contact with faeries was never like Disney, there was always a sting somewhere in the mix.
I love it. The black branch looming across the frame, with it's bare tentacles about to snatch the unsuspecting/looking-the-wrong-way/pensive princess adds a lot of tension to the photo.
