Step 6: On either side of Goku's head draw an arc similar to the letter C as guides for his ears. Goku has pretty big ears, so don’t draw the guides too small.
Step 7: That's it for the initial sketch! You have the basic Goku shape, so 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 8: Darken the shape of Goku's eyes and make them a bit bigger. Inside each eye draw a half circle and shade it in for his pupils. Add a few sketch lines under Goku's eyes for extra detail.
Step 9: For his eyebrows, draw a thick rectangle-like shape that kind of looks like a check mark above each eye. Furrow his brow a bit by adding a few lines between them. This gives Goku a determined look. Maybe he’s about to go Super Saiyan!
Step 10: Right above the smallest construction line, draw Goku's nose. His nose is similar to a diamond or an upside-down kite with the left side shaded in.
