In this step we're going to draw a large ball for a start. This will be the base of the whole body. Next is to draw three circles for the three heads. Add the guidelines as shown. These are used to draw the face with ease. I use these guidelines all the time to help me level out the eyes, mouth, ears, and noses equally. Add three lines ascending from the lower body. These lines are going to be the Cerberus's legs. At the end of the lines make ovally circles. These will be the bases of the paws. All the way to the right, add a curved line for its tail.
