The background of this composite image is a close-up shot from a couple of years ago of part of a sculpture at the Seattle Art Museum. It was the pyramid shape that lead me to create the image and call it Caravan. (At first glance, the Fashion Queen thought she was looking at camels.)
Staying with the pyramid interpretation, I see the fading shadow and the darker marks in the upper left quadrant of the image as an approaching sandstorm. That made me think perhaps the caravan ought to be disappearing into the storm. That led to the version of the image below. If you care to, let me know in the comments which you prefer. I’m quite torn between the two myself.
