Lines and Reflections
A backlit scene with filtered light coming down through the trees illuminates fallen branches in a pond full of leaves. There's a lot of brown in this image giving it an overall harmony.
I think really it's about the lines of branches and reflections in the water which are mostly organic and vertical against the few straight horizontal ones across the top.
Of course the most sunlit branch leading in from the bottom left leads the eye into the frame, but I don't think it too strong to distract attention from the remainder of the image.
