Look for an opportunity to create a white path into the composition and link the whites into a single shape. If you allow the whites to separate each one could fight against the viewer's attention, and the composition could lack unity. I am not necessarily talking about the color white. I am talking about lightning the values you use, to create a viewer's path, to bring the eye to your focal point.

Once you have your white and mid tone paths, you can complete the composition framework by adding darks. The darks do not need to create a single path. The reason is that the eye seems to connect darks even if they are not literally connected.
