Step 2- Add the actual eye itself
a dbz eye is usually pretty strange looking but it can be drawn fairly easy.
Step 3-add in the pupil usually it will just be a semi circle but this eye is a ssj4 one.
Step-4 Shade in the eye/Color it.

The next to step in drawing a manga eye is to make an arced line across the top of the circle and then a line down to represent the eyelashes.


Now add a lighter tone of the color you picked and add some black lines around the bottom of the eye.
Now all thats left to do is to add some line around the eye to show the wrinkles and folds people have around their eyes.
