Interesting B&W. Personally, I wouldn't mind seeing a colour shot as well. The problem with the first one, as I see it, is that the mid-ground tree, to the left, blends in with the background, suggesting that there isn't enough contrast to make the image "pop". It also suggests to me that this may be one of those shots that just doesn't make a good conversion to B&W - not every image does. My 0.02¢ FWIW.
