The may or may not be compositions, but they are organized enough to be readily recognized and they do incite an emotional response.
This is a really intriguing comment. If they may be a composition, who is the composer?
I admire and get beauty out of nature, too, but I don't attribute intention to those patterns, colors, sounds. A sunset, to me, is not saying anything even though it's beautiful. But some hear the "language" or "meaning" of nature (or God/gods) so I would want to remain open minded, here.
