Awesome work. But I think you're missing an Autobot. The three Autobot cars in front of Roadbuster, and Whirl. I think their was a forth on. A red Cybertronian race car bot. He was really crappy looking. I don't see him in the picture.
I can even name them, too: Powerglide, Jetfire (or Skyfire), Omega Supreme, Cosmo, Beachcomber, Seaspray, Blaster, Perceptor, no idea who the other Autbots in the Top Row are, Slag, Sludge, Grimlock, Swoop, Snarl, Warpath, Inferno, Red Alert, Tracks, Smokescreen, Hoist, Grapple, Windcharger, Bluestreak, Brawn, Hound, Trailblazer, Bumblebee, Jazz, Ironhide, Ratchet, Prowl, Wheeljack, Cliffjumper, Mirage, Huffer, Gears, Sunstreaker, Sideswipe, and, of course, Optimus Prime.
