Step 15: Draw a series of wavy lines between the ears for the front part of the pegasus' mane. The lines should come to a point. They should also turn to the right because the mane is blowing in the wind. Don't draw every individual hair strand, just the basic shape of the mane. The shape should go over the eye.
Step 16: Use the initial circle and arc as guides to draw the rest of the pegasus' head. Follow the basic path of the guides but draw an extra bulge on the top left side for the other eye. Make the lower part of the head a bit narrower than the guide lines. Follow the edge of the initial circle on the right side to create the jaw. Add a series of lines within the shape of the head for extra detail.
Step 17: Use the second line from the left under the body as a guide to draw the pegasus' first front leg. Lightly sketch the shape of the folded front leg as you follow the basic path of the guide line. Wherever the leg bends should be more bulbous to represent the joint. The hoof should be square-like. The section right above the hoof should be thin. The base of the leg, the top part, should be thick. Sketch lightly so that it's easy to erase if you make a mistake. Darken the lines only when you get the shape right.
Step 18: Now use the leftmost line under the body as a guide to draw the pegasus' other front leg the same way. Follow the basic path of the guide as you draw the shape of the folded leg. The hoof should be sqaure-like, and the top part of the leg will be hidden behind the body.
Step 19: Use the line under the body on the right side as a guide to draw the first hind leg. Lightly sketch the leg around the guide line. Use curved lines where the guide bends to inidicate the joints. The pegasus' hind legs are stretched out, but they should still bend a little near the middle for the joints. The top of the leg should be wide. The hoof should be square-like, and the bottom should point to the right. When you get the structure of the leg right, darken the lines.
