The different shape are written on the side. One to Three is the basic shapes, Four to six is are hybrids.

With different shapes of the eyes, i drawn each one with different emotions- to make it more challenging. My coloring skills is a bit rusty but i give it, my best.

When start first drawing the basic eye shapes- I drawn up top/number them, so i know what shape to draw. The eye shape that i draw below was just sketches for potential hybrid eyes.- If that helps anyone else. As an example.
