Looks fantastic (and i saw it as well at CGTalk - where it looks as good! :-))) ) What worries me always is what happens to these clouds when they go into another atmosphere - and/or have to be scaled. Or transformed (moved, rotated etc). Better fuzzy material support for clouds, smoke etc is very very high on my wishlist for e-on and future Infinite versions.
