im going to take a gander and say that the guy is really mad at his significant other, went for a walk to ease his mind. and lost his anger while throwing rocks?
but then again with the costume and the color scheme im thinking more of a 1920's love story where this is actually a metaphor for him throwing his heart away?
Could have called it "Well dressed angry man with hat, at beach throwing rock at something that made him angry, but that we cannot see". But that's a bit wordy.
Bryon, its a nice image irrespective of the name. I am nevertheless amused watching
folks here attach significance to the image. I like the vignetting as well.
