Step 6: On either side of the head, at the top, draw a small arc as guides for the yak's ears.
Step 7: At the top of the head, draw two lines that curve outward and then up as guides for the horns. Place the yak's horns near the top edge of the circle. You can draw the lines longer for longer horns.
Step 8: Draw two vertical lines under the first circle as guides for the yak's front legs. Bend the lines near the middle to indicate the joints and at the bottom for the feet.
Step 9: Draw two more lines under the second circle as guides for the yak's hind legs. These lines slope a bit to the left before bending near the bottom for the joints and feet.
Step 10: Draw a couple of lines that connect the first two circles to complete the guide for the yak's torso. Curve the line at the bottom as a guide to draw the low-hanging fur later. Draw a big, tall arc to connect the head to the body for the hump. At the bottom, draw a shorter line for the yak's neck.
