I luv OPTIMUS PRIME but never draw a decent artwork of him.
When I first saw the new animated tv series I thought the style is too simple, but stil I'm okay with the characters' concept especially Optimus Prime, Prowl and Bulkhead. Later on while surfing the net I saw the prototypes of the new toyline based on the tv series.
The designs totally AWESOME! Personally I think they're way better than the original designs in the series...And my favorite definitely the Optimus Prime!!!
After that I took a piece of paper & started to sketching my own version of TFA's Optimus Prime...1st I wanted to draw exactly like the toy version but then I decided to put more animated looks on it. Finished it with photoshop in 2 days, I really luv it and I think it's decent enough to show it on Deviantart.
hopefully , I can draw the other animated Autobots later...
