Ironhide- added the yellow stripe to both sides of the vehicle mode, painted his forearms red, painted his shoulders black, gave him a silver face, and swapped the bumper and thus chest plate from Ratchet.
Ratchet- painted the rims silver (forgot to mention that on Ironhide), painted the brushguard black, painted the red panel on the roof and painted-in side window white, swapped the bumper and chest piece with Ironhide, painted the forearms white, and painted the head crest black.
Ooh, I really like how you painted over the windows on Ratchet. Really helps give it more of an ambulance feel.
It looks really nice what you've done here. Good job! Also, I like your sig It reminds me of how much I love that light blue on Thundercracker!
