Wonderful colours, very close to the originals and thus seriously nostalgia-inducing!
Back in the day, I considered the 1ed Cybertronic faction a weaker one, sculpt-wise, but they are certainly growing on me, especially since they are not as stylistically tied to the Warzone universe as the others (e.g. WW1 aesthetics in space, more shoulderpads than on an 1980s Ladies' night at the discotheque).
