Good Composition
This photo is an example of good composition, because the focus is on the subject. The depth of field focuses on the flowers rather than the background. Our eyes will focus much more on the flowers instead of a cluttered background that takes away from the subject. The subject is also a good distance from the camera. This photo is taken with a wider aperture as well.
