I looked at the three pairs of images in the link, and the first thing I notice is that in none of the pairs are the two photos truly taken from the same location. Same general area, yes, but not the same location, as when looking at details the perspective in each photo of the pair is different. I'm not sure that simply being handed a (out of focus in one case) cell phone shot of a location is really going to help anyone assess a location for possible use as a photographic location. If one were truly trying to suggest that some people have an eye for composing a beautiful image, and that others simply suck, should not both images also include the human subjects? Without the subjects being the same it seems a completely pointless exercise. Getting any scene to work is usually an exercise in placing both the subject and the camera to provide the best perspective, as well of course as the ability to control the depth of field, and even the lighting. The more you shoot any particular type of subject the better, and therfore quicker you are likely to become in realising where you are going to want to place both the subject and the camera for best results.
