Step 20: Use the angled line on the left side of the body as a guide to draw Elastigirl's first arm. Follow the path of the guide and lightly sketch the shape of the arm around it. The shape should be thinner at the wrist. When you get the arm right, darken the lines. Make the lines curvier where the arm bends for the forearm's muscle structure.
Step 21: Use the circle at the bottom as a guide to draw the fist. Follow the basic path of the circle but make the shape of the fist more blocky. At the bottom , draw a series of short lines to separate the folded fingers and knuckles. At the top, where Elastigirl's arm bends, draw a line for the top of the glove.
Step 22: Use the initial triangle shape as a guide to draw the upper torso. Draw a curved, horizontal line near the middle for Elastigirl's waist. Follow the path of the guide on the right side but curve the line out more for the chest. Inside the torso, on the left, draw a curved line to finish the chest.
Step 23: On the chest, draw the "i" for the Incredibles logo. Add a curved shape on the right. The bold letter i basically consists of a small circle with a small rectangle below it. Add a curved shape on the right. The top of this shape should be thin and the bottom thick. Draw another curved shape on the left. This time the top part should be thick and the bottom thin.
Step 24: Use the V-shaped line on the right as a guide to draw Elastigirl's other arm the same way. Lightly sketch the shape of the arm around the guide. When you get the shape of the arm right, darken the lines. Curve the lines near the bend for the muscle structure and make the wrist thin.
