Next step: darkening the eyes and adding more shadow. Also, draw the eyelashes from the root(eyelid), as you can see, they're really big, so you have to be carefull 'cause you don't have to exaggerate.The lower lashes should be thinner and shorter than the upper eyelash. Don't forget to shade in the upper lid and the eye angle. Draw the lines around the iris, these lines should should look like rays radiating out of the pupils. Darken the upper portion of the iris of both eyes.
