This photo submitted by Andreas Schumacher doesn't do anything for me. Yes, the horizon line follows the rule of thirds but other than that, what else is good about this photo? The cow in the foreground looks out of place, almost like it was pasted in there. The cow's face is too dark to see much detail in the eye and it's out of focus. I'm not sure what would make a more interesting photo here. Maybe sharp detail of the cow or a whole field of them grazing would be better. I would also suggest trying a different composition.
