How to draw a realistic eye

Start like so

Add the under of the eye

Add the inner eye like so

Draw the waterline inside the bottom eye line you already drew

Draw the outside of the iris

Draw and fill in the pupil like so

Put a little bit of shading in a crescent form at the top of the iris

Shade the outside of the iris like pictured and put where the white of the eye shall be. you will not put any color this area

Put little streaks coming from the pupil

Shade it a kind of crescent gradient from the top

Make the top line darker

Put in a bit of shading on the sides of the eye

Continue shading and put an outline around the iris

Start off the eyelashes like this. These parts will be most prominent. Draw very lightly and with little strokes

I know this looks ridiculous, but I want you to put a few more of the eyelashes in between the big eyelashes you already made

Start filling them in

Do kind of the same thing to the bottom eye line

And fill them in

Now, I didn't do this before the lashes and I should have, but you draw the crease above the eye, you could do it a different way but this is the way I chose

Shade in up to the eye like so

I accidentally deleted the first part of the eyebrow process, but just try to follow the shape and strokes as you can

Start filling in the eyebrow hairs. They don't have to be perfect and they don't have to go inside the line, normal eyebrows are not perfect!

Kind of do the same thing to the top part where you do not stay inside the line and make it look natural

Keep filling it in the front and bottom

Now, is example or strokes, fill in the entire eyebrow

Now kind of fill in very lightly where you want the shadow to be

And use your finger to blend it out

Continue shading get as you wish, and maybe even put your own spin to it! I hope you had fun and learned a bit from this step-by-step
