@MadScientist: That's an insightful interpretation. I wish now that I'd seen it that way myself and used this image as the last of the series.

@JoeB: I can see how it seems that way, but this image would actually fall somewhere in the middle of the order taken. I took some images one night at high ISO, processed them, and then on another night went back with a tripod (though I also shot some high ISO images). This one was actually shot as the sun was setting, on my second or third night (out of four), before I brought out the tripod.
