What program are you using? Looks pretty cool, just have to slap some colors on to get more feel to him.
One small suggestion on the arms in the rear view. You have the three panels on the outside of the fore-arm, and I think just to make them look less flat maybe angle them a little to contour the arm. Should add a little bit of depth.
Really liking it, but I was thinking, why don't you add some kind of Asterix-ish helmet wing to mimic the G1 headwings?
I'm liking the way it looks so far, but if you really want it to fit in the Bayformers world, he's got too much body armor on. A few more added random bits wouldn't hurt either.
just tryin to change him up as much as i can to fit the bay-former style, you should see the mirage i have planned, his upper half is normal, but from the waist down hes like centaur but with wheels (kinda) XD
