I think that the photographer used symmetry, overlapping layers and depth of field in this picture. The way that they capture the person in the middle of the bridge emphasizes the size of this insane looking bridge that is over a ton of trees. They are also telling a story in the fact that the subject is walking to what looks like a home. The fog bank coming in from above breaks up all the trees that are surrounding the bridge and house. The use of color in this picture helps keep your focus on the center of the image.
