I love the deserts of the American Southwest, especially at sunset. While I much prefer clouds at sunset, sometimes a nice rich blue gradient sky can complement an orange landscape. I waited until the shadow being cast on the rear cliff was high enough to see the full silhouette, and then the sun went behind a hill very rapidly.. I had just a few moments to get enough shots for a panorama before it all fell into shadow.

You might try to make the horizon line straight.
