Step 15: Follow the path of the small circle to create the Grinch's hand. Curve the edges more as you darken the lines.
Step 16: Draw a series of short, curved lines along the shoulder for the suit's fluffy collar. The Grinch's collar should extend from the left side of the shoulder almost down to where the arm bends.
Step 17: Darken the top of the small circle for the back of the head. On the right side, make the Grinch's head thinner by drawing the edge closer to the eye. Make the bottom wider for the cheek. Add small, angled lines to the cheek for fur. Draw the bottom of the head between the lip and collar. Draw a curved line on the top, left side for the Grinch's other cheek behind the collar.
Step 18: Add the Grinch's other hand below the head by drawing a couple of wavy lines inside the small circle for the fist. The wavy lines create the knuckles. Inside the shape, draw a couple of short lines for the folded fingers. To the left of the fist, draw the Grinch's thumb as a small, curved, pointy shape. Add a couple of curved lines to the left for the fluffy wrist. Draw the thin arm around the guide line.
Step 19: Draw a series short curved lines above the top oval for the fluffy part of the shoe. Draw the shape of the Grinch's leg around the angled line. Curve the shape of the leg to follow the path of the guide. Add a few short, angled lines at the top for the fur on the leg. Darken the oval at the bottom for the shoe but make the tip pointier and curved.
