This time I actually took some pictures on how I do my eyes.
First the most important thing is to get a good reference, specially if its a known character.
add white to the inside of the eye. Some people mask the white of the eyes before painting the skin tone, but its much easier for me to just painting over skin :D
The base color of the eyes. I know it looks kind of weird right at this point, but I promise that it will look better later :D
