Begin by drawing a lemon shape-NOT AN OVAL! Sketch in a circle for the iris. However, it is not a full circle, part of it is covered by skin

Add some eyelashes. Some prefer to do this in the beginning of the drawing or the end. It's your personal preference!

Begin to shade in the pupil and iris. Take your time on this step

Play with some graphite! 😏

Shade in the outer skin around the eye.

And you're finished ! Nice job !
