Nice vista. My problem with TG clouds is the clamping of fractals with the cloud node. Top and bottom. I have a sneaky suspicion that this scene won't look as good if you panned the camera around. I have some ideas on how you might be able to cookie cut the cloud tops to get some more variation, but always end up with the same problem of adding billows to a basic cloud shape. I have an R&D day tomorrow I'm going to have a play with this, if you're on msn, give us a shout.
