This document provides tips for painting eyebrows and eyelashes in a realistic way: - Eyebrows are unique to each person and not perfectly uniform, with hairs pointing in different directions. They should be visible but not solid. - For eyebrows, start with an outline layer as a guide, then add hairs within (feminine) or filling (masculine) the shape. - Eyelashes are thicker at the root, thinner at the ends, and don't all face the same direction or have uniform thickness. Build them up in layers for realism.
