For Transformers one, the art department aimed to create shapes and silhouettes that appeared clean and simple from a distance, yet included intricate, purposeful details up-close, such as cut lines in the panels, smaller inset geometry, and layered panel work. Given that iconic Transformer designs often stem from their helmet shapes, the art department worked to seamlessly integrate faces into the helmets, enhancing their expressiveness while maintaining a mechanical, rigid aesthetic.
