Some characteristics of design in this photograph include:
Color: The image is mainly white besides the bright blue and orange structure in the center, which immediately captures the viewer's attention.
Shape/Texture: The image is very minimalistic, causing it to have mainly linear shapes with a smooth texture.
Contrast: There is a sharp contrast between the tower and the small flags. Not only because the orange flags stand out against the bright blue towers, but also because the towers are very structured, while the flags are free-flowing.
