When presenting a documentary or technical photo, it may be enough to present a reasonable and accurate view of a place. A fine art photo, on the other hand, has to elicit interest that makes the viewer want to engage with it. The idea we are putting into it may be described as emotion or feeling, but I think it is perhaps better to use the word meaning. A photograph may express the magnificence of a fiery dawn or the grandeur of a place or the personality of a person, and that it what engages us. Sometimes a snapshot may express these ideas, without there being thought behind it, which is part of the appeal of dramatic locations, as they to a certain extent, speak for themselves, but it is still the photographer's job to make the technical and artistic decisions that cut through the static of reality, to represent what we originally liked in an interactive, three-dimensional environment in a static, two-dimensional space. From a compositional standpoint, we react diffferently to a static, two-dimensional image than to the real world; from an artistic standpoint, the difference between average snapshots and fine art is that the first only has significance to those who bring significance to the image, whereas the latter should bring significance with it. Going into making the photo with the idea that you are trying to create something meaningful makes you think about what you are presenting in terms of how it is goign to convey interest to the final viewer, and informs your compositional decisions going into the image. In the case of the image you mentioned, think about what you thought was special and worth recording about the location, then think about how the image conveys or fails to convey such ideas.
For me, a foggy forest conveys a sense of calm, interrupted in the photo by the abrupt perpendicular of the fence, which also distracts the eye to the lower half of the frame--perhaps having it run out into the distance and be lost in the fog would enhance that idea. I am not saying that this is possible in this location, but I give it as an example thought I might have when composing. Not to say that I am great, but I think I am at least getting better, and thinking like this is a real help to me for the kind of problem you are having.
