Taken by William West, this picture is successful because it has a nice color scheme, and it has been edited in a way that makes each color and shape pop.  The concept of this image is a flower as the only thing in this picture with the sky as a background. The colors complement each other, the yellow is emphasized against the white and the white pops against the blue, and i really like how the stem of the flower is black to match the insides of the petals.

This image is asymmetrical because of the stem on one side and not on the other. This photo shows unity because the stem goes toward the flower, and then the petals all lead to the center of the flower. I think this photo emphasizes the yellow in the middle of the flower because ether yellow is so bright and it has a noticeable texture.
