How to draw eyes

When focusing on the details of the human body, the first order of business is the most important feature of the face: the eyes. Eyes can make a character look beautiful, seductive, evil, insane, charismatic, or determined. Well-drawn eyes give characters that extra sparkle that makes them memorable.
Remember that the eye is a three-dimensional sphere inside the head. The eyelid is tugged over it. It's this stretching of the eyelid that creates the almond-shaped look of the eye. The upper eyelid slants down severely near the tear duct. Both upper and lower eyelids have thickness, so each is drawn as a double line, or with one thick black line to indicate lashes. The lashes become thicker toward the outer edge of the eye.
The eyebrow is drawn on an arch that dips at both ends. Try practicing the eyes on this page. The various angles and expressions will give you a greater understanding of the form.
