Yeah it definitely looks really nice and flattering, you probably wouldn't have a hard time selling it if that's what you're interested in. I kinda wanted to see it go to night though, but that's a lot of footage to take heh.
The clouds are really awesome, and you get to see exactly how they cast shadows. Keep it up.
I've shot some clouds, as well as a full moon recently with clouds blowing by in front of it at night ... looked cool (did the same as you, speeding one up 1,000% and another 10,000% in post.
That said, I never had the optimal clouds & setting you did, so I don't think they look nearly as good. Your's looks REALLY sweet. Crop that into wide screen, and you might be able to hide the traffic.
