Instead of using only an outline, what is a better basis for sketching the nose?

Correct answer: Light and simple planes

The governing concept is that a nose is a three-dimensional form, not merely a boundary. Its bridge, tip, wings and underside can be understood as simple planes receiving different amounts of light. Begin with light construction and plane changes, then add restrained tonal shading. Therefore option A is correct. A dark nostril line alone is only a detail, while paper texture and hair direction do not describe the nose’s structure.
