I love the smooth sky and the feel it gives. For some reason my eye keeps getting drawn back to the lost details in the shadows bottom right. Overall I do like the shot.
Nice. Can you post gear and EXIF info? Hard to make some constructive suggestions without that.
As far as the final result, I love the leaves in the tree on the right... but I don't see how they relate to the rest of the image. I'm speculating that a stronger comp would have been to take 3-4 steps forward and compose as you did, but without the tree.
