Bulkhead, human

Yes I think Bulkhead's black. His age, his deep voice, his bigness; it's like how Jazz can't be anything but black!

Good thing I had gesture drawing earlier this week in class, otherwise those muscles would've come out all weird. And I don't know why, but my calves keep turning out looking AWESOME! So beastly! He gots big feet like mah daddeh.

You have any idea how many times I've listened to Thunderstruck by ACDC while drawing this?

It's 10 PM, guys. Hopefully I can sneak in some more human Autobot drawings while at school. Possibly Decepticons, too. (For an art teacher who worked for Hasbro he sure does hate cartoons...) Anyone have suggestions as to draw Optimus' face? I'm just not sure if I should put in facial hair or, if I do, what its style should be. After all, he's a truck and an army boy.
