Step 16: Darken the backward C-shape to create Steven Universe's ear. Draw a series of short, curved lines to draw the small afro-like hairdo. There are five bumps that go around the head to create Steven's hair.
Step 17: Use the line and circle on the right side as a guide to draw Steven Universe's arm and hand. Follow the basic path of the line as you make the shape of the arm thicker. Add a line in the middle to create the sleeve. Draw the folded fingers within the shape of the circle as a series of small, curved lines.
Step 18: Use the initial circle as a guide to draw Steven Universe's shirt using curved lines. Inside that shape, draw the T-shirt's star design. Use the picture above as reference to get the shape of the star right.
Step 19: Draw the arm and hand on the left side by using the initial line and circle as guides. Follow the path of the line as you make the arm thicker, and draw a curved line near the middle for the sleeve. Use the arc as a guide to draw the shapes of Steven Universe's fingers using a series of short, curved lines. Add the thumb too.
Step 20: Use the lines under the T-shirt as guides to draw Steven Universe's pants. Follow the path of the lines as you thicken up the shapes of the legs. Draw a curved line at the end of each pant leg for the cuffs and a couple of lines near the top for the zipper cover.
