Figurative planes are no different than the planes that make up a honey comb, a nautilus shell or a sweeping landscape. One last thing to consider when rendering value planes is the weight of your lines. Be aware of the pressure you are exerting on your pencil as you create the value plane lines. Vary the lines. This makes it easier to differentiate between the planes, create connections, and accentuate the space. I like to emphasize the points of intersections on my planes and let the line get lighter as it moves away from the intersections. This gives the drawing weight and dimension. By varying your line you can push and pull the space and therefore make it much more interesting for the viewer.
Continue developing the concepts of this lesson with Directional Hatching and Cross Contour in Figure Drawing, which shows you how to fully render planes using directional hatching and cross contour.
