I'm interested in creating an effect similar to the one linked below, but freehand drawing with perspective isn't my strong suit. Looking at this image it appears that I could individually create the constituents pieces, and then map the islands and icebergs to the surface of the sphere before "wrapping" the cloud pieces around all of it.

But, I have no idea how to go about this in Illustrator...any help?
