First, draw the guidelines. Draw the top and bottom like how big you want your eyes to be.
Then, draw two ovals, right on the borders of the guidelines.
Add the eyelids. Notice that they are ALMOST touching, but they aren't.
Now draw in the iris. I like to make a dark ring around it, because it just looks better, but that's optional.
Now outline the highlight. The thing when it comes to highlights in manga eyes, people put in too much.
Here is me, doing the hardest part. The gradient.
Here it is with the other eye. It looks better because it's bigger.
Add details to your eyes. Add the lashes, eyebrows, and finish the rest of the face.
Now erase the guidelines before you add hair.
FINISHED DRAWING. Happy Sketching! ✏️
