I took this photo in Los Angeles over spring break. The building on the right is The Broad art museum. This image represents the rule of thirds by having the two structures on each side with the sky in the middle. This divides the image into thirds.

The Diagonal rule is represented by the lines on the building on the right. If you look at them closely the diagonal lines cross each other and can send the eye on a z-axis.

The diagonal lines on the structure to the right also represent graphical vectors that have a strong sense of direction. These vectors encourage eye movement out towards the sky.
