Below is a step-by-step drawing tutorial.
Draw the base of the eyes. Use light lead
For the pupil and the iris, draw two circles.
Darken the pupil, and add light streaks towards the iris.
Add a little “halo” to the pupils and streaks.
Draw more streaks beyond the halo.
Mark the first set of streaks or pupils by blending everything together.
Darken your eyelids and add eyelashes.
Lightly shade the eyes with a light pencil.
