Realistic portrait drawing involves capturing the
subject's unique features, such as their bone structure, skin texture,
and facial expressions. It also involves paying attention to the
lighting and shadows that create depth and dimensionality in the
portrait.
To achieve realism in portrait drawing,
artists must have a strong understanding of anatomy, proportion, and
perspective. They must also have a keen eye for detail and be able to
observe and replicate subtle nuances in the subject's appearance.
