I think its an improvement for sure but not quite there, the colors seem to be washed out and kind of bland, which leads me to think that it might work pretty well as a BW shot. I would try converting to BW and playing with the contrast a little to make the river really pop against the snowy banks and gray sky.
I recently spent a day hiking after the last big snowstorm we had and was having the same problem since there is so little color to be captured with that type of landscape and sky. I got a lot of the ones I thought were junk to work pretty well by doing what I stated above.
Just my .02, most important thing is you get something that you are happy with.
