Add details to the face, such as wrinkles, beard texture, and the expression in the eyes.

Refine the drapery, adding folds and highlights to create a sense of volume.

Adjust the values throughout the painting to enhance the contrast and create a sense of depth.

Add final details and highlights to complete the painting.
