I enjoy the way the sunlit gap in the immediate foreground, with its red leaves, relates to the gap in the canopy of the tree -- and how the black trunk of the tree relates to the branch shadows coming up from the ground. it makes for a very complete and active image. My only suggestion would be to check out reducing the amount of blue sky above the tree. By cropping down to almost the top of the tree, one's eye is drawn up and down from the ground to the tree top then back again. The blue sky , as it is now, also works great -- but instead of my eye being bounced up and down, it tends to rest -- almost nested -- in that bare area of the tree.
