It is not always you get perfect sharpness, composition or snow. But sometimes it ends up perfect anyway. This Photo is slightly out of focus and it is also tracks in the snow but does it make the photo bad. I don't think so, sometimes it just works anyway and this is one of those times.
One thing that annoys a lot of photographers, including me, is when you don't have sharp images looking at it at 100%, so called pixel peeping. But truth to be told sometimes you just have to let it go and zoom out a bit and look at the image as it is. If it is good who will complain? Maybe that out of focus or other faults is the thing that makes it stand out.
