I like this shot. I might consider shifting the composition a bit to the left to include the entire first ring. Again, however, the assignment was to use a small aperture (F22) to capture ALL of the rings in focus.
Nice image. I would love to see your F-stop number on this and then compare it to your specific plane of focus. If you had a high F-stop (F22 or higher) your plane of focus should have been just beyond the first white dot in the composition. That would have allowed better focus in the foreground while keeping the background adequately sharp. Another though would be to have the person on the steps stand and fill the white space for a nice compositional element.
