How to draw an eye

Start off with a lemon shape...

Add in the iris and pupil, leaving white areas as light pockets.

Lashes vary in length, bottom lashes should be relatively short if you are going for a natural look. Everybody's lashes are different so go crazy!

The shiny pen was annoying me so I went over in micron pens... Shape your eyebrow any way you prefer, I did a simple arch.

Colour any way that fits your character! :-)
