I like the idea and glad you shared... With a lot of my shots of clouds/skies I like to not have to many things really close up, leave the trees and other objects out further in the landscape. I think the main point is to capture the entire sky...
One thing that is hard to do and i think you did a pretty good job is capturing the actual colors, although I imagine there was some brighter pinks in that sky. I can just see it now...
