I have this idea for Optimus Prime but I've only doodled the head in my spare time. So I decided to flesh it out using paints etc. The idea was to make him a young-ish character yet have traits that showed how the war has ages him prematurely and this is shown for example under the eyes. I used aspects of the mouth plate to give him features such as the top of the mouthplate for a nose and the bottom as a goatee which gives his a more youthful face. I tried to keep the head compact as it's believed that with people short hair give people a grown-up look. This means that there isn't any extra things trailing behind the neck. As for the the antennas, I had an idea to convert these parts to give Optimus a "crown" appearance on the head which signifies his lead of the Autobots. The colours therefore follow suit with Royal Blue being used as the blue on his body. I do plan on drawing the full body at some point but for now I just want to introduce the design.
