That's it for the initial sketch! From this point on, press harder with your pencil to get a more defined sketch.

Step 6: Draw the gorilla's eyes inside the head using the lines as guides for placement. The shapes for the eyes are similar to little footballs. Inside each eye, draw a small circle and shade it in for the irises. You can leave a tiny circle unshaded to represent glare or reflection. Draw a few small lines around the eyes to indicate the wrinkles. Above each eye, draw a line to indicate the thick brow and add more small lines for extra detail.

Step 7: Draw the gorilla's nose under the eyes. Use the lines as guides for placement. Draw two small arcs for the nostrils and shade in the space under them. Draw a curved line on the left and right side of the gorilla's nostrils for structure.

Step 8: Draw the gorilla's mouth under the nose. The mouth itself consists of a wavy line. Draw a broken line under it for the bottom lip and another curved line under that for the chin.

Step 9: Draw the ear on the right side. It's basically a curved line with quick, short strokes on the left for the hair.
