This is a realistic drawing of an eye, I used only graphite mechanical pencil with 0.5mm diameter
I started by drawing a round circle and drawing a diagonal line across it depending on how I want to elevate.
Then I started shading, I started with the pupil and then the Iris
I added some highlights to make look realistic. Then l shaded the Little meat beside the eye
Then I shaded the eye ball then I went ahead to shade the external part of the eye.
Then I drew the eye lashes with "j" like shape
After drawing l added more shading to the and then I had my final result
Thanks for viewing my post have a nice day
