This is incredible! The only change I would really appreciate is that you set a specific key to change the scene, not all of them, because if a player is in full screen and needs to task switch or wants to take a screenshot they lose the city they're observing. (I figured out a way around it but it's cumbersome.)
I love the audio design. You really captured the ambiance of Blade Runner and I like that at least some of it is dynamic, such as with the big ships. (I'm assuming it's a combination of procedural and dynamic but I'm not entirely sure.)
