This is a very nice shot. The snow really adds to the shot and makes it look more beatiful and natural. I love the lines you can see in the railings. This shot is so georgeous. I love the angle from which you shot this. Nice job.
This would have been a fantastic shot if the crop was a little tighter on the bridge itself and at an angle that excluded the bushes. Still a great shot.
Love the snow, love the idea. Almost like a post card. But you seem to have fallen into the trap that gives a snow scene blue cast. Try tweaking the levels just a little bit.
One set of foot prints leading from the bottom left over the bridge might add more interest. I think the B&W works well here, although the frame doesn't...
