There. My small small contribution in exchange for viewing your image.
This really is all about the trees, their formation overhead of interweaved and interlaced branches ... the symmetry of nature. Really nice.
I, too, would like to see more of this scene from you. And besides the obvious of the fall colours, I am wondering what the capture would look like if the forground was just at the start of the more shaded part of the tunnel. Would it add another dimension or change the feel?
This has a feel of being very open and inviting. Again, nice.
