I gave this a 9. Maybe it is a little dark, but that doesn't bother me. I've seen enough snow to know that it's really really white. I don't need that from your photo. What I do need is a sense of story/mystery. This has got it. I love the background/ middle ground/ foreground, how each has something to say.
Very monochromatic even though the 'sluch' has a hint of color. There is no real focus of attention, nothing for the eye to come to rest on here. Compositionally this needs a lot of work. Maybe a Red ball thrown into the scene, whith a little snow on would have given this another level.
