Step 15: Use the angled line on the right side of the body as a guide to draw Luigi's first arm. Darken the line but extend the line farther right at the bottom. Make the line curvier too. Draw a thin, short shape at the bottom and on top of the initial circle for the top of the glove. Add a few short, curved lines on the left to make the arm thicker. Draw the hand at the bottom inside the circle. Make the hand thinner than the circle. Add short, curved lines at the bottom for the folded fingers.

Step 16: To the left of the completed arm, inside the body, draw a small circle for the overall's first button. Draw a long, curved line around and above the button for the overall's first strap. Below Luigi's chin, draw a thin, short shape for the shirt's collar. Darken the left side of the guides for the overall's other strap. At the bottom, draw a small oval for the other button. Draw the rest of the strap on the left. Add short, curved lines at the top for the top of the overalls. Darken the left side of the initial circle for the body.

Step 17: Darken the line on the left for the visible part of Luigi's other arm but make the line wider. Use the circle at the bottom as a guide to draw this Nintendo video game character's hand. Add a short, curved line at the bottom for the visible finger.

Step 18: Draw a couple of lines around the guide on the lower, right side to create the shape of Luigi's first leg. Don't make the shape of the leg too thick. Darken the oval at the bottom for the shoe. Make the bottom of the oval a bit flatter. Add a line at the bottom for the sole of this Super Mario Bros. character's shoe.

Step 19: Draw the shape of the other leg around the line on the left. Keep the leg skinny. Draw the bottom cuff over the oval and make the line curvier. Darken the oval for the shoe. Draw a couple of short lines under the oval for the shoe's sole and heel.
