Sometimes it needs a different approach to extract a subject from its surroundings. Here it is clearly the cloud that is my subject, but by using a mid-range or wide angle lens this was not obvious. The cloud would have been a small band above the horizon. I zoomed in at 500 mm with the Sigma 50-500, usually my workhorse for wildlife photography, and suddenly the cloud really became the story telling element in the photo. Sure, this photo is about a mood, but without the interesting cloud it would have been just another plain sunset picture.
