Contrast can be such an important piece of composition. In this image, I love the contrast between the cold and dark metal of the chain linked fence alongside the sunny and delicate bloom. One doesn't take away from the other, not at all. They compliment and enhance each other. They can be very different and live alongside each other, touching, doing what they are intended to do, amiably. One without the other would not be so interesting, so engaging. Kind of like us, no?
