Thanks to feedback I received, I implemented several suggestions on this winter scene.

1) 3:2 aspect ratio suggested by Starless. Works nicely because now I got more attention also onto those tire tracks on foreground.

2) Black and white suggested by Valfal. This is a good subject for B&W altogether.

3) Kind of HDR effect suggested by Adrian Bollans. Although, I used "channel mixer" on GIMP set for 0 red, 100 green, 0 blue. That brought some more contrast and details into forest.

4) Composition balanced to the left, suggested by Jon Smith. And also the house on left cropped away, which others also suggested if I remember right.

Thank you everyone for your feedback =)
