This does look like wintery, cold and barren. Because the tree can't be offset to thirds, I think it would have been better symetrical so the crop was equal on both sides of the tree. Otherwise, well done.
Great subject. I'm a little confused about why you've chosen to crop part of its branch structure on the left, and leave whitespace on the right. Would be nice to keep it all in the frame.
I like the tree but the background would have made a great landscape picture as well by itself. any way, good view of the whole tree, it could have been a little more centered.
