Study real eyes from reference photos
Observe the eyelid shapes carefully
Draw the eye socket before the eyeball
Keep both eyes aligned on the same perspective
Match the size and spacing between the eyes
Draw the iris as a partial circle under the eyelids
Place the pupil in the center of the iris
Add the tear duct near the inner corner
Show the upper eyelid thicker than the lower eyelid
Indicate the fold above the upper eyelid
Use the eyelids to wrap around the eyeball
Add highlights consistently with the light source
Shade the whites of the eyes lightly
Darken the upper lash line for depth
Draw eyelashes following the eyelid curve
Vary line weight for a more natural look
Keep the eye shape unique to the character
Check symmetry without making both eyes identical
Refine the corners and edges for realism
Practice drawing eyes from different angles
Compare your drawing to reference and adjust proportions
