In this tutorial, we learn how to draw Optimus Prime of Transformers. Start off by drawing the outline of the entire body of the character. Make sure to add in the large arms and feet as well. Next, draw over this to make a more elaborate outline including the details for Optimus Prime. Once you have all the details draw, erase the background lines. Ten, color in the character and add in lines and shading to make it look more realistic. Once you have done this, then you will finish off with any last details and add a background to it as well, enjoy!
