In this tutorial, we learn how to draw Optimus Prime, leader of the Transformers. First, draw the outline of Optimus Prime, use basic lines and circles to show where the joints are going to go. After this, draw the full outline around the character, using a dark line to make it look 3D. Then, draw in the rest of the details for the character, giving him a look like a machine or a bunch of metal. Next, you will start to shade in the different parts and add colors that were used in the movie. When finished, color in the background and save.
