Optimus Prime - Instruments of Destruction

I was totally listening to the OST of this incredible movie while drawing this!
I, am huge fans of the original TF, though he likes everything else, especially when it's Optimus related!, but who doesn't like Optimus?
This is the colors to my originals

Pencils - fav.me/d5taplz

I was originally going to paint this the way i paint all my other drawings, but then i decided to try something different, and did a bit of cell shading. It really makes the robot look all roboty
