The document provides 20 guidelines for creating correct art that demonstrates techniques like depth, distance, and three-dimensional form. The guidelines cover techniques such as using foreshortening when drawing objects at an edge, using shadows and shading to show light and dark areas, adding contour lines to show objects as full rather than flat, manipulating the horizon line and level of detail to indicate distance, and drawing overlapping and larger objects to depict relative closeness. The final guideline notes that the rules can be broken when there is an intelligent, logical reason to do so.
