Hi JT, huh, that's an interesting trick with the mountains. It certainly will save you some time. One thing I notice about the land clouds layer is that it seems a bit stretched along the horizontal axis. This may not be a big issue, but if you want to generate clouds that are not stretched, make sure that when you are rendering the clouds that you change the default X and Y size settings (in the Noise pop up window) to adjust for document sizes whose Height and lenght are different. For instance, since you have here a map whose length is greater than its height, you would need to increase the X size to compensate. Hope that helps. Oh, and thanks for the kind words on the tutorial, I'm glad you are finding it useful.

Cheers,
