I believe this photo (above) is a
good example of
poor structure. It is unclear what exactly I was trying to capture as the subject just by looking at this photo. Since I took the picture, however, I can tell you that the grave stones were meant to be the primary subject. This photo is poorly structured because the subject is cut off at the bottom in a very abrasive fashion, and the subject does not take up enough of the frame to draw the viewers attention effectively. Instead, the concrete wall of the building behind the grave stones takes up the majority of the frame. Those are indeed bullet holes in the wall overlooking a war memorial; this information makes the subject more interesting, but only after it is revealed to the viewer. The photo itself does not really communicate anything to the viewer in terms of what exactly they are actually viewing. I think this meaning could be conveyed more appropriately by structuring the photo more effectively.
In comparison, I believe the photo seen below is a great example of good structure. The kayaks in the lower left-hand corner of the frame could very well be considered the primary subject(s) of this photo. However, this is not just a photo of some kayaks; it is a photo of kayaks in the context of a beautiful ocean-side landscape. I think the water is framed nicely by the trees, foliage, and the other island across the strait. The kayaks are situated nicely in the grass, pointing into the water; however, the kayaks are fairly small inside the frame so as not to take anything away from the natural beauty in which they exist in.
