For the rear leg on the close side, draw a long oblong shape for the thigh and a rounded rectangle for the shin. Place a shape for the foot at the end of the shin. The front leg should have a circle for the shoulder, a rounded oblong shape for the upper leg, and a rounded rectangle for the lower leg. Also add a shape for the foot at the end of this leg.
In the next step, we'll add spikes to this dinosaur.
