Profile of an old man

Create a light outline of the head and neck, paying attention to proportions.

Establish the basic shapes of the facial features: nose, mouth, eye, and ear.

Begin adding layers of cross-hatching to define the shadows and forms.

Use darker lines to emphasize the deepest shadows, such as around the eye socket and under the chin.

Soften edges and blend values by lightly layering more hatching.

Add details to the facial features, such as wrinkles and the texture of the skin.

Refine the overall drawing, adjusting values and adding subtle details.

Add a light wash to the background to create depth.
