Beech Tree in Snow BW

I've begun working on BW interpretations of floral images. Here is an image of a beech tree on a hillside covered with snow taken in 2012. In addition to converting to BW, I have taken some other minor liberties with the processing (a more literal version of the original image is in my gallery), but I figure I can still post it here rather than PA. I have also just posted a more photo-artish (but color) version of this in the PA gallery. Beech tree, Mill Creek Park, Youngstown, D700, 180 f3.5 @ f8, 1/250, iso 250, single image, converted to BW. Please view large. Suggestions and other comments welcome.
