This Could be an example of fill the frame because the picture is completely consumed by the moving water and the shoreline. Also for some reason, the center point of interest happens to be right in the middle of the picture.

I thought this was a good example of leading lines. When looking at this picture, your eyes are forced to move along the shoreline. Its very hard to avoid not following along the shore.

I thought the guy on the bike was good example of the rule of thirds. The focus is definitely in the left third and is not in the center point.
