I can see why you spent two hours here, the pattern in this image is pretty fascinating. I like the arrangement of the pattern created by your composition, nicely seen.
Like Bill P I see valleys which is the beauty of photos like this; you can lose yourself in the fractal ambiguity. I like taking them too, but my friends just look at me weirdly when I show them: “its bark Col, have another drink” unless they are artists or photographers. Love it.
A very cool abstract, Stefanie, with excellent depth of field which adds to that ambiguity others have discussed. The moss really makes the image in my opinion.
