humanized optimus prime

This week's humanized G1 Transformer: Optimus Prime. Holoform if you prefer.

I wasn't originally planning to do Prime, but I got so many people asking that he got added to the list lol. Thanks to ~twistedcortex for the suggestions on how to do him, I didn't exactly use them all, but they made for a good jumping in point.
All of the G1 Transformers I've humanized are here: Sunstorm Optimus Prime Rumble & Frenzy Jazz Ironhide Soundwave Skyfire/Jetfire & Starscream + 2013 version Starscream

used: pen-tool over tablet sketch

comments before faves please!

*edit* Please please please stop comparing this to every character to ever have a beard! It is based only off of Prime's robot form and not meant to look like anyone else!
