Gradually we are beginning to add details, step-by-step. Designers often refer to the window as the DLO: the daylight opening. I think this term was invented so that we could have conversations no one else would understand. The DLO on the 911 is iconic and very different to a Cayenne or a Panamera, since they are four-seaters. This is one of the first details I add, followed by the front headlamp, and then more detail at the rear end. You can see the shape of the bumper has been added, and the rear lamp.
