I'm still in the early Photoshop design phase. My intention is to make him a real dumb brawler with a very bulky, gorilla-ish frame. He transforms into a black Peterbilt semi (pretty much the same model as Optimus) oil tanker truck. I will update as I make more progress. UPDATE: Fully blocked in colors. Moving on to rendering. UPDATE #2: Closeup of main body w details (hi-rez).
