Self-portrait, Known as the Young Warrior

Lightly sketch the basic shapes and proportions of the figure, hat, and background.

Begin adding the darkest areas using dense, overlapping lines.

Gradually build up the mid-tones by layering lines with varying density and direction.

Use cross-hatching to create darker values and define forms.

Pay close attention to the direction of the lines to convey the form and texture of the hair, clothing, and hat.

Use lighter, more spaced-out lines to create highlights and lighter areas.

Refine the details of the face, paying attention to the subtle variations in value.

Add final touches and adjustments to balance the overall composition.
