Step 15: Use the line on the left as a guide to draw the other leg the same way. Lightly sketch the shape of the cassowary's leg around the guide. When you get the structure right, darken the lines. Make the bird's joints bulbous. At the bottom, draw an extra-long triangular shape for the blade-like claw on the inner toe. Draw the visible portion of the middle toe using a curved shape with a pointy tip.
Step 16: Use the remaining shapes as guides to draw the rest of the cassowary's body. At the top, darken the outer edges of the guides to create the back. Along the bottom edge, draw a series of short strokes for the shaggy feathers. The longer these strokes are, the shaggier the cassowary's feathers will appear to be. On the right side, draw a curved line made up of short strokes for the bird's tail.
Step 17: Carefully go over the final sketch lines with a pen, marker or any other type of permanent ink. Don't push down too hard with your pen. Ink lightly for less pronounced lines. After inking, get rid of every pencil mark for a cleaner drawing.
Final Step: Color your cassowary drawing! Use light and dark blue for the bare skin on the head. Use light blue at the top and dark blue at the bottom. Leave the sides of the neck blank. Use red for the blank areas on the neck. Blend red, orange and yellow in the casque. Color the bird's eye yellow. Use gray for the rest of the head. Leave a strip blank on the beak and casque for shine.
Use gray for the top part of the bird's body and then continue with black at the bottom. Color lightly at first. Then gradually build up to the level of black that you like. Cassowaries have dark plumage, so push down on your pencil to get a dark black. But leave the top lighter for shine. Use light brown to color the cassowary's legs. Use gray to create some shadows on the legs. Use gray for the claws too but leave a strip blank for shine. Use gray and a bit of purple to create a cast shadow under the cassowary. It's always a good idea to use reference as you draw. Remember to pause the video to draw at your own pace.
