Thanks!!
No AA was used in this render. With AA the scene becomes much smoother of
course.
The saguaro still need some attention indeed.
You know, it is mostly trial and error to get this, and trying different
types of functions and their combination. But the tutorials help, yes,
Christoph's, and Mike Williams' too.

The advantage is that you don't have to create everything from scratch. Some
are quite detailed, a few have errors, but overall, I am quite satisfied
with them. You still can buy the collections, even with little harddisk
space. Just use the included CD's when you need them.
