Gather reference photos of a real eye
Use a smooth drawing surface and sharp pencils
Lightly sketch the eye shape and eyelids
Mark the iris, pupil, tear duct, and eyelid creases
Check proportions and symmetry before shading
Block in the darkest areas first
Shade the sclera lightly, keeping it off-white
Draw the iris with radial strokes from the pupil outward
Add the pupil as a deep black circle
Leave bright highlights unshaded
Build layers of tone gradually
Darken the upper eyelid shadow
Add reflections and catchlights in the eye
Texture the eyelashes with varied lengths and directions
Shade the skin around the eye with soft transitions
Blend carefully while preserving detail
Add fine wrinkles, veins, and subtle color variation
Increase contrast to make the eye look realistic
Refine edges, sharpness, and small details
Erase small highlights to enhance realism
Compare the drawing to the reference and adjust as needed
