Step 10: Inside the head, on top of the horizontal line, draw a couple of small shapes for the Grinch's eyes. Draw the eyes on either side of the vertical line. The bottoms should be round and the tops thin and a bit pointy.
Step 11: Between the eyes, draw a couple of curved lines for the Grinch's furrowed brow. On top of the eye on the left, draw the eyebrow using a series of sloping lines. Fray the top of the eyebrow. Add the eyebrow on the right the same way, only the top part will be hidden under the hat. Inside the eyes, near the top, draw two small ovals for the pupils.
Step 12: Between the eyes, near the bottom, draw a small, triangular shape for the Grinch's nose. Draw two tiny, curved lines along the bottom for the nostrils. Add a longer, curved line below the nose.
Step 13: Draw a wavy line from the bottom of the original circle to the horizontal guide line for the Grinch's smile. On the right side, draw the other side of the smile the same way using a couple of curved lines. The smile should be similar to a wide letter V. At the ends of the smile, draw a couple of curved smile lines. At the bottom, draw a line that's somewhat parallel to the smile for the Grinch's lower lip.
Step 14: Use the L-shaped line under the head as a guide to draw the Grinch's first arm. Follow the path of the guide and draw the shape of the arm around it. Curve the top part for the shoulder. Add a couple of short lines where the shape bends for creases. Keep the edges of the arm close to the guide so that the overall shape is long and thin. Draw a series of short, curved lines on the end of the shape for the fluffy part of the Grinch's suit along the wrist.
