When doing outdoor photography we usually see tiny details in the photo which could be better, but having said that I think that this is the closest to a "perfect" photo of a frost covered tree that I've ever seen!
"I breath the cold air in, let it embrace my lungs and I feel the ice deep inside me."
I love this picture by the way, it's really really beautiful and somehow chilling.
Cold, silent beauty.

What I do not like is the asymmetry of the tree in the lower third of the picture as there are far more branches and twigs on the right side. Although I have to admit that this covers the right-shift of the illumination in the background.
A minor technical remark: In the sky at the lower right side of the image there re some dark spots which I would have removed.
And thank you for using only a small watermark which does not disturb from the image
