I forgot how much I love drawing eyes!
Especially with pens ;)
Step 1 - Eye shape
Draw the top and bottom lids of the eye, leaving the bottom lid split in two, slightly curved lines.
Add the outer iris, imagining a full circle with the top hidden beneath the eyelid.
Then add the pupil, leaving an open-ended triangle on the top left part of the pupil (this will be a highlight later).
After that, draw the crease of the upper lid.
Draw some eyelashes! Start from the top of the eye and create some small, graceful lines that curve upward. Try to make them overlap the eye just a bit, to show that they grow out from the top lid.
Do the same for the shorter eyelashes on the lower lid.
Time to darken the pupil.
Here, I made the top three quarters of the pupil as bold as possible. Careful not to hit the highlight!
I left the bottom quarter of the pupil lighter than the rest, and added some very faint curved lines on either side of the pupil. This will act as the less-noticeable highlight in the eye. If I'm being too detailed, no worries. Just pen in the entire pupil and forget the highlight!
Draw the outline of the highlight as faintly as possible. Very simple. It's basically a curved rectangle
This part is different for every eye I've drawn.
First, make sure you don't pen very much on the bottom right part of the eye!
Now that I've given you that warning, all you need to do is lightly pen some small zigzags randomly between the pupil and the outer iris.
Start at the top of the eye where the shadow will be darkest. Lighten your shading as you near the pupil. Leave the highlights completely white.
Draw a fine eyebrow. The deepest part of the eyebrow is on the left, curved down to where the nose would be. The arc of the eyebrow sits over the rest of the eye, ending in a fine edge on the far right.
Add a bit of shading to the upper lid, and you're done!
