I agree with what others have said, truly awesome. Again, a real winner here. Bless you for daring the cold, in those conditions, frostbite of bare skin can happen fast and I'm glad neither of you were hurt seriously by the extreme cold. Personally as a photographer, I would not have done it, I just can't ask a model to be so exposed in such extreme cold. I'm not judging by any means, I just could not have done it. I love doing photography and will do a lot to get the shot, but I just can't put a model at risk.
You both are very brave souls and deliver awesome works together and I applaud you both for your commitment to your art and yes, what a story that image will bring to you both in years to come. The memory will always be priceless.
