Step 6: That’s it for the initial sketch! You have the basic Hiro shape. Now go in and tighten your drawing. From this point on, press harder with your pencil in order to get darker lines and a more defined sketch.
Step 7: Darken the shape of the half-circles inside the head to create Hiro's eyes. Make the top part of the eyes thicker to represent the eyelashes.
Step 8: Inside each eye, draw small circle for Hiro's irises. Inside each iris, draw an even smaller circle for the pupils and shade them in. Add yet another even tinier circle inside each iris to represent glare.
Step 9: Close to the bottom edge of the main circle, draw a couple of small lines for the bottom part of Hiro's nose and nostrils. The lines should be right on top of the vertical construction line.
Step 10: Now add the sides of Hiro's nose as small curved lines and draw a slightly longer line above the nostrils for the tip of the nose.
