The limited colours made this picture attractive to me. Just the white of the snow and the shadows are blue light reflected from a clear winter sky.
The photograph has an abstract quality, it is very difficult to know what part of the landscape this is. The composition is very simple too. the repeating horizontal lines are the first thing the viewer notices and this gives the sense of calm.
The viewer then notices the detail within the horizontal elements, there are lots of complex shapes within this seemingly simple picture. Looking closer you will see lots of snowflakes. This is not the snow as it fell but is caused by partial melting and recrystallisation of snow over several days in very cold, dry conditions.
