How to draw chibi anime eyes
Add a lighter shade of that colour you coloured the top of the eye with. Colour the rest of the eye with that colour
Yay, blending! Blend the two colours ^_^ or if you're drawing it in pencil, you can smudge the colours
Now add two white dots on the eye, one slightly bigger than the other. If your drawing in pencil, you might want to make these dots using whiteout, that's how I sometimes do mine!
