In this step, the coloring begins! First, color the pupil completly black, but leave the point of light you drew white. Don't leave any spots where it looks fuzzy or scratchy. Next,pick a color(blue, green,brown, gray, etc.If you want a more exotic look, you could do an unnatural color like purple.) and fill in the iris. I can not stress this enough when I say color OUT from the pupil, straight oyt. It's tempting to fit your coloring to the curve of the pupil/iris but don't. If you look closely at your eye you'll see it looks like lines coming out from the pupil. That's the effect you want. Now color the lid and waterline a skin tone, but color with the curve of the lid. Color the tear duct a light reddish pink.
