Eventually we'll get a video of the day/ night cycle out there, I think. We're just getting going on the parameters. But it does make a huge difference.
If at all possible could you take a video of the city as seen from a stationary spot in the hazard zone or the lake so you see the entire city throughout the entire 24 hour Day night cycle? Condensed down to around 20 seconds or so? Maybe the opening part of your video?
Also we need an updated high resolution city shot of the city from that spot. the one you have is over a year old. and the buildings no longer match.
