Step 10: Use the initial arc as a guide to draw the rest of the beaver's muzzle. Use quick, short strokes as you draw the mouth and chin to represent fur.
Step 11: Use the arc on the beaver's head as a guide to draw the ear. Make the top of the beaver's ear a bit more pointy and add some lines inside for the inner structure.
Step 12: Use the initial circle as a guide to draw the rest of the beaver's head. Follow the basic path of the head but make it bigger than the circle. Use quick, short strokes as you draw the shape of the beaver's head for a furry texture. Draw a long curved line using quick, short strokes on the lower left side for the strong tree-cutting jaws.
Step 13: Use the lines on the right as guides to draw the front legs. Lightly sketch the shape of the leg as you follow the guide. Darken the lines once you get the structure right. Draw the beaver's feet by drawing a series of short curved lines at the bottom. Use the other line to draw the front leg on the other side the same way. Use quick, short strokes on the legs for a furry texture. The beaver's feet are basically hairless.
Step 14: Now use the lines on the left side as guides to draw the beaver's hind legs. Remember to sketch lightly at first as you follow the basic path of the guide. Darken the lines only when you have the structure right. The hind feet should be a bit bigger than the front feet. Most of the hind leg on the other side is hidden behind the body, so only draw the foot.
