Choice of colour temperature is different - and quite effective. Lends a mystical quality to the subject, makes the first perception one of a landscape rather than a detail, which I quite like - in fact I'd go so far as to say you might have cropped this to contain only the tree, and lose the sky and stuff top right of frame. DOF is a bit too shallow to really show us a breadth of texture - it rather concentrates on a very narrow area bottom third of frame, but there's still great interest there. One function of this colour that I don't like so much is the coldness it brings to the image, but that's inevitable. Intersting.
