This is a beautiful landscape. From the looks of this over-all, I think it's quite good in many ways. I hesitate to share my opinion on this simply because I'm sure it is as you want it to be, and it is good.
My preference would be to add just a little more contrast to help with the dark snow on the bottom, and to add a little more saturation to make the sky brilliant so it isn't just another sunset. I'm giving this a 7, which is a pretty good score. The overall shot just looks a little flat to me. I do love the composition.
Very impressive shot of a winter sunset/sunrise. The snow in the composition really helps to give a sense of coldness and the sun gives a warming feeling. Your eyes are lead from the bottom right toward the bridge with the help of the bank of the river/bay/body of water.
