Yes that's a genuine moment captured there, i'd not change a thing apart from the crop...
The aspect ratios of almost all digital/film slrs are close to that of the golden rectangle, it was not by accident that Oskar Barnack came up with the 3.2 aspect ratio when he invented the first 35mm camera, it was designed to be as close as possible to that of the golden rectangle
Pythagorus came up with the ratio. It is said to be one of the most athstetically pleasing of all geometric forms. Example of it can be found Greek architecture. The Parthenon in Athens was built to the dimensions of the Golden Rectangle.
It's one of main reason's why Henri Cartier Bresson never ever cropped his images.
I always find it a shame when i see the ratio changed, which is one of the reasons i was not crazy on the magic guy cropping my image.
Sorry for the ramble
