Zenon,
I like the the way the tree's play off of the sky...There is a certain richness here...I wish that the right tree branches were all in the frame. The dark spot in the road is distracting to me...but I see how the composition came together with the other background elements. The tree's alone may have carried this image, but I will defer to see what others think...
Hi Zenon, Exposure is beautifully handled and a great subject for B/W. The trees really pop and I also would of liked to see the tree on the right not cut. If this were mine I would have given it a bit more room on the bottom and added more room on the left to get in more of the road. Nice image!
Everyone is on the right track here. The trees on the right should be completely in the frame (assuming that something did not exist out of image that caused you to frame this way). I would have also include more room at the bottom as the trucks are too close to the bottom edge. I like the tree in the far BG on the left as it help to balance the image with the road but would have included just a bit more than that. The road is a great leading line that adds depth to the image and visual interest on the left.
Jerry mentioned the dark spot. I agree it does catch the eye as it meanders down the road. You could clone some snow into it if that is something you don't have an issue doing, but all in all I don't think it is a big deal.
Well done on the exposure and overall tonality of the image.
