Humanized Optimus Prime

Originally I was going to do sketches of multiple humanized transformers, but I got as far as Prime and Prowl but then Jazz completely stumped me. So I coloured in my Prime sketch to practice doing humans. I think it came out well, though the hair looks a little flat. His shirt was a bit of an afterthought.

And I plan on (finally) doing the requests now. This sidetracked me for a bit.
