Because it is ages since I last drew an eye in a larger format!
As some people suggested; I drew one of the images I took of my own eye
I had fun with this, but I wasnt too hard on myself when it came to details.
A4 Cansons drawing paper
Mars Lumogtaph pencils and Polychromos coloured pencils
Erasers and blending tools
Here is the reference image:
