The eye is essentially a ball in a hole. The whole area is in shadow.
The eyes are in the middle of the head – midway between the top hairline and the chin. Mark the keystone which is a trapezoid shape which starts the nose and separates the eyes. The eyebrow is the top of the keystone.
Tear ducts point down. The outer corner of eye is slightly higher than the inner corner. There is a 45 degree angle from top of brow (top of keystone) to tear duct. Top part of eye ball will be darker than bottom because it is covered by lid. Lashes and pupil blend together. Eye lashes are drawn as one mass in a ribbon shape. Do not paint individual lashes.
