I really don't see why we need to change the background buildings in that scene, they could use some of Ady's colour correction, sure, but I don't see anything wrong or outdated about them.
The sky and *some* of the buildings in the back do scream matte painting, but I really like their designs. And I think that changing them with generic buildings would take away from the beauty of this shot.
Just my two cents if course :)
