"I used to think it was a terrible thing that life was so unfair. Then I thought, 'what if life were fair, and all of the terrible things that happen to us came because we really deserved them?'

I decided to close those side panel's to mimic Spoiler's flat black headpiece. Painted stripes green for detail. Painted the top of his helmet silver, and the front of his helmet green to mimic Spoiler's featureless bland green visor.
My paints were bad and the silver sucked. So I may get some better, brighter paints and touch it up. And may add a few more green details elsewhere to bring it together.
Added black to their cars, to make them different than Sideswipe and Sunstreaker.
Well, mine aren't hard to do, and they look amaturish. At it's base, these are just a headswap and using the base mold's color. Minor paint to just liven them up. Easy enough. You could do this. Anything harder is beyond me.
