Draw an oval-shaped head. Using a light pencil, dissect the head with both horizontal and vertical lines to divide it into equal halves. Draw the cave woman's eyes on either side of those lines' intersection. Add the nose by drawing a flat line halfway between the center and bottom of the head, and draw the bottom of a semi-circle under the nose to form the mouth.
Add a neck directly under the head, and from this neck, expand out to shoulders, and then arms. In your early drafting phase, the arms should consist of two long, thin rectangles of equal lengths. For hands, sketch an oval-shape with four fingers and a thumb.
Create a torso by drawing an hourglass shape under the shoulders. Add long rectangular legs with oval-shaped feet.
Draw the cave woman's outfit over your sketched outline of her body. Use jagged lines to create a rustic, primitive shift dress, and add a pattern by adding rounded spots.
Fill in and finalize the cave woman's arms, legs, hands, feet, and face, either with a pen or with paints.
Add wild hair. Draw a hairline just beneath the top of the head, and extend the bottom edges of the hairline down, nearly to the shoulders.
