I love the cold, blue mood you have captured. I am not so thrilled with the overlap between the interesting foreground branches and the interesting background trees. Perhaps if you lifted the angle of the shot slightly to put the branches in front of the blank snow, it would have been improved.
The exposure and focus is excellent. The color is used to dramatic effect. Details of the ice and snow on the twigs are very sharp. Sharpening is perfect for online presentation.
