Balance: Instead of looking at one thing, the eye scopes the entire frame. The two courts are similar, evening the plane.
Unity: This bunch of rose captured together represents unity. Although they are different colors, they are all still flowers.
Movement/Rhythm: The running/walking boys portray movement. Because there are multiple of them, attention is carried from one running boy to the next.
Contrast: Against the green grass and brown tree trunks, the semi-bright blue bench stands out.
Pattern/Repetition: The windows on the ceiling appear over and over in the same design. It is a strange and invoking pattern because of all the other surrounding windows.
