The image looks too digital. It doesn't look realistic enough. My favourite wallpapers from your entire collection have been ones that take an unrealistic scene and make it look real. I like fantasy and dreams and I would love it even better if the fantasy and dreams actually came to life.
The trees here look too digital rendered. The snow looks fake really. It doesn't have that fluid, natural feel to it even though the overall image gives off the feeling of having a stroll down a path in the woods during winter.
