Thanks Bill! I have eroded the landscape some more, following Marc's
comment.

I have trouble to get the perspective right, i.e. the feeling of sheer size
of the landscape (that is why I introduced the balloon). That is something I
shall have to work on. I have already reduced render time somewhat by a
better use of isosurface parameters, so I can concentrate on this.
Vegetation in the foreground is certainly an option; Water, I have
considered and I may try that as well.

Absolutely! That was already on my todo list. I have been experimenting with
a height_field in the background to get a better horizon and atmospheric
perspective, but that is not yet really satisfying.

So simple really! Now, one has to be careful not to overdo it!  :-)

Sure! Will come!
