Don't get me wrong, you have done an excellent job and I'm impressed by your
craftsmanship. The point I was trying to make is that you can actually see
that the picture is created by joining several photographs and not a
seamless panorama shot. If that is what you want, than it is fine. I prefer
seamless panos that is taken with a real panorama camera, or stitched
digitally with panorama software.

The ?bug? is not the DOF but the kinks in the railing. It reveals that it?s
not a seamless pano.
