The city models are the free ones by Dystopia. I didn't use any textures for them (they wouldn't be visible at all).
You may notice that these are the same clouds like in my 15°C image. I just like them!
Critics welcome, but probably there won't be an update, because all in all this one took more than 100 hours to render (I used some high settings: Render Detail 0.8, GI 3/2, 64 samples for the athmosphere and for the clouds more than 770 samples!)
