Rejected for multitudes of reasons, but the one I am curious about is "quality" and sharpness. I don't understand how to improve sharpness. This was shot at the lowest iso level, 1/800 second, F/7.1, and I distinctly remember the sun being to my back. The shot was underexposed by about a stop, but I know my camera well enough to know it can handle a stop of underexposure.
