Portrait of Pellerin, actor of the Palais-Royal

Lightly sketch the overall shape and proportions of the head and shoulders.

Establish the main lines of the facial features (eyes, nose, mouth) and hair.

Refine the shapes and proportions, paying close attention to the angles and curves.

Begin adding shading to define the form, starting with the darkest areas.

Gradually build up the values, using cross-hatching or blending techniques.

Add details such as the wrinkles, hair texture, and clothing folds.

Adjust the values and refine the edges to create a sense of depth and realism.

Add the signature and the date at the bottom right corner.
