I played the anim using Windows Media Player. YouTube's version is a little jerky. It played just fine, even at slower speeds. It would be better if it was longer (of course everyone says that). The only reason it needs to be longer is the transition upwards as the clouds build. The new 'boils' seem to just appear. When you are ready to use this in the next full landscape render/anim I would add 450 more frames.
I am really impressed. Very nice work.
