as much as we focus on what is actually visible in camera, we do give some love to the city at the sides and behind the camera. it doesn’t have to be the exact same buildings as in real life, not even the exact location. it just needs to be close enough in style and size. add a few low-poly trees and lamp posts, even a few low-poly people. these will give some play in the reflections and some ambient shadowing or light bouncing for a more convincing render.
