I was not able to vote on this challenge, but if I had, I probably would have given you a 6 or 7.
Technically speaking, this is a wonderful photograph. The framing is perfect, the exposure is great, and the choice of duotone simplifies an otherwise busy scene. The thing I like the most about this photograph is the contrast between the dark sky/buildings and the bright white snow. While it is an awesome image, and it does have a few stars in it, there are some other images I would have scored higher based on the fact the stars were more dominant. There are a few images which have less of a star pressence, but the images would be significantly different if you removed the star(s). I think your image would hold up on it's own if the stars were removed. This is would stop me from giving your image one of my top 3 votes.
Overall, great image, and congrats on your top 10 finish.
