I this photo, the principle of design, rule of third is being used. The grids of the rule of third crosses on the center of the zebra, making the photo mroe intersting by breaking the balance. The horizontal lines also spits up the backgrounds in to water, soil, and grass background. The nose of the zebra is on the bottom horizontal line same as the bird on the left side of the photo. It emphasises the size difference by having them starting at the same height. The color of the bird beak and the zebra face also make them self stand out from the plain brown color of their surroundings.
