With that scene, Joe, I was working around the cattle positioning. Placing them on the third lines, very roughly. I never try to force a natural scene into strict placements but the general idea usually has some advantages. So cropping from the sides (either side) would mean getting them too close to the edges. It did take a bit of time to get those awkward creatures into some sort of a suitable position. My request to 'Move closer together' just fell on deaf bovine ears.
Also, I wanted to show the full cloud height, so that was another limiting factor.
