I think its pretty, but there is not enough of a story going on, just a tree in the snow. Have you though of adding some elements to the illustration, I don't know what it could be, maybe playing around with the bird a bit more...
I like the simplicity of the design and the effect of the almost "unfinished" "painted" edges of the image. I think the tree itself needs a bit more tweaking. Some branches look a bit too thick in comparison with the "older" branches and the tree trunk.
on a side note, its supposed to snow 14 inches where i live tonight.
