I love the wintery landscape and all the details of their clothing, boots, gloves! that lend it the nordic feeling.
I adore the ravens, and their names! Those birds always do seem as if they know something, dont they?
bearded!Snape is really gorgeous, even without the long hair I adore so much. For all the AU elements, their connection is so very Snarry: calm, clear, strong, deep feeling and loyal always, that's our Prince.
