I've got the file, and I'll try it soon, because I'm at the library.
But I gotta admit too, once I saw SF Night Cloudy, its exactly what I expected it to be. Great work mate!
EDIT: I've been busy on MM2 checking out the skies, and they're so amazing!
I assume you're gonna work with the sky reflections on the water for the next version, right? Might be a suggestion, but upto you.
On a scale to 10, I rate this 9.9/10.
