Richard, yes, they do all of the graphics in house. These guys are very much inspired by the G1 toys so you can defiantly see those influences 
I worked on Ironhide and Hound as well but they changed a lot on the way to production.
One of the fun things about consulting for such a big brand is seeing all of the things they do with the collection to tell the bigger story of these characters. In this poster you can see Sideswiper and Red Alert (another G1 character, same tooling as sideswipe, but done up as a fire chief’s car… must be a posh fire department ) along with Prowl, Ironhide, Hound, Prime, and Chromia.
