Portrait of a Negro, Orlovski's Servant

Begin with a light sketch of the overall composition and proportions.

Establish the main shapes of the head, hair, and clothing.

Block in the darkest values using charcoal or dark pastel.

Add mid-tones, gradually building up the form.

Use hatching and cross-hatching to define the planes of the face and create texture.

Pay close attention to the highlights and shadows to create depth.

Refine the details of the eyes, nose, and mouth.

Add final touches to the hair and clothing, capturing the texture and movement.
