Jerzy -- Great work. I've seen many images of Bryce Canyon over the years; however, I don't recall seeing a composition such as this one. This image is certainly not cliché. It offers a fresh compositional perspective to a beautiful, much photographed area. I especially like the backlit tree. As Paul noted, it adds a perspective of scale that helps the viewer appreciate the enormity of this landscape.
Stunning photograph, lovely warm tones and such a confusing image, I thought that it was a cavern opening at first, half-flooded until closer inspection. Good work, love the little tree!
