Thank you very much for your suggestion, Slobodan and Dave
Too bad I don't have a model release from her.
It was not a staged shoot, I was photographing the ice formations and details on that ice hill, when the girl walked in. I took 3 quick snaps of her, this one being the only useable.
The flying cape was pure luck, she lifted it from her shoulders just as she walked through the gap between the ice blocks.
