There are several ways to learn how to paint a person. Painting the "indication" of a person is probably the easiest. While painting a portrait of a person will take a bit more study, time and practice.

When painting eyes in a portrait, eyelashes are sometimes the final touch and can make or break your work. All eyelashes are not created equal. Sometimes just a few strokes of the brush is all that is needed to give the suggestion of lashes. Other times it is necessary to delicately detail lashes since that is the feature you want to stand out.
