It seems as though the snow has been overexposed, so that all detail has been lost. I think that a touch of addition al sharpening would help a little as well.
It's so hard to shoot in snow! I can't give much good advice, but I see the same kind of issue in this as in my snow shots. That is, it's a little over-exposed. But I do like the way the person in red pants stands out so much in the white.
To me, there's a little too much space at the bottom of this photo. I'd probably crop it just below the last guy, and maybe try to catch the tops of the lights on the bridge. It's nice and crisp though.
I guess I won't be the only one to say this, but the snow & the sky are both blown out. Title works. Cropped too low. Cutting off the lightposts detracts. Might be too much snow in the foreground.
A little too bright and not enough definition and contrast. Very over-blown in areas. Suggest taking images at sunset or sunrise instaed. You'd get a much nicer image in better lighting. I've shot here (in Ottawa) and know this to be true.
