As for the topic of “what is the main subject”, I have always thought of it this way… The elements of a composition consist of a main subject, a supporting cast and any number of neutral objects.

A supporting cast object is something that enhances the image with its presence but the image could stand up if it wasn’t there.
The main subject is simple. It’s the one thing that “has” to be there. Without this element, the image has no compelling reason to exist.
