This is a fine example of when a great collection produces awful advertisements.
I like the idea of playing with snow in heavy, fancy clothing, but who are they trying to fool with that powder? Maybe I'm paying too much attention to detail, but that "snow" is terrible and as a result almost ruins the pictures.
The colors are truly the highlight of these and give off a sort of "cold" feeling, which I think was the intent. I really enjoy how the background fades from the corners to the middle. That's a small, nice touch.
Yana's expression in the second advertisement is terrible, for lack of a better word. The first picture is improved from that, but she still looks as if she's frozen solid and can't form a solid facial expression. Maybe that's the whole idea!
