Here's a study in value patterns from Tuesday night. The drawing above exhibits good proportions in relation to the page (this includes the cast shadow) as well as rich, full and balanced values. Notice how the strong contrasting black background enhances and complements the lighter value of the "paper wall." Dark shadows within the "wall" help draw the "eye" inward and balance the background with the cast shadow in the foreground; in a sense creating a bridge between the two spaces. A particularly nice touch is the way Frank exaggerated the depth of the paper by highlighting and creating a slight cast shadow along the top edge of the paper.
