Step 6: Draw a thick, angled line shape on top of each eye for Sub-Zero's furrowed eyebrows. The shape of the eyebrows should come to a point on the sides. Between the eyebrows, draw a couple of small lines for Sub-Zero's wrinkled skin.

Step 7: Darken the football shapes to create Sub-Zero's eyes. Inside each eye, draw a circle for the irises. Inside each iris, draw a dot for Sub-Zero's pupils. On the side of each pupil, draw a tiny circle to represent glare.

Step 8: Drawing Sub-Zero's mask is a bit tricky, so it's divided into five steps. First use the lower arc on the head as a guide to draw the outline of the mask. Use the bottom part of the original circle as a guide for the top of the mask that looks similar to a wide letter W. Then follow the path of the arc and make the sides more angled as you darken the line.

Step 9: Draw the mouthpiece where Sub-Zero's nose and mouth should be. This shape is similar to a long pentagon. Add a a diagonal line to each side corner of the pentagon.

Step 10: Inside the pentagon shape on Sub-Zero's mask, draw three shapes that are similar to boomerangs. The top shape should be bigger, and they should get smaller as they go down.
