This was pencilled by the amazing Ben Hansen.
This took me about 8 hours maybe more. There are parts that I'm not quite happy with but I thought I would post it see what you guys thought. I will revisit it next week so that I don't over work it now.
Hope you like it, comments welcome
EDIT: Made an alteration to the lighting on the chest plate, didn't quite fall properly before. Also added some detailing to the bolts and some "rust" (not that Optimus would rust), probably dirt then, to bring it together more.
