STEP 2: After your background is dry, begin to pencil in the face. When you feel ready, take a pencil and a good white eraser and draw the face in faintly and loosely. Take a dark paint pen (I used black in this example) and begin to outline the features of the face. Work slowly and carefully. Less is more when working on the face, and layering little by little really helps. We are not aiming to make this face perfect but artful and expressive. I feel any quirkiness or eccentric details help to make it that much more endearing. Take a small round brush loaded with paint or ink and fill in the lips. I like to make the upper lip slightly darker than the bottom, as itâ€™s usually under a shadow.
