In this video we learn how to draw the iris of an eye. First, draw the outline of the eye and then draw the first layer of crosshatch on the eye. This is just diagonal lines overlapping each other. For the next step get out your 3B or 2B pencil and go over the first layer that you just made matching the tones of your reference image. Then, add in the darkness for the pencil making it completely black. Leave a square on the upper corner of the eye that is white to create a glare. Then, add in pre-shadow to the eye and continue to detail until it's to your liking!
