The plant is intended to be a "Satin Pothos".  I had modeled it for another
scene a while back and just reused it by adding another vine and redoing the
splines that define its path.

As for rendering time, I have gotten used to a workflow where when I'm finally
done with the modeling, textures, and lighting I just let the rendering begin
and hope there aren't any pathological pixels that never finish.  Usually I'll
start it before the weekend, better on a long weekend, and just let it run.

For really long renders, longer than a weekend, I'll start another scene in
another instance of POV-Ray and just let it go in the background, or I'll pause
the render if its interfering with something else I'm doing and resume it later.

While I'm working on a scene, I break almost everything out into its own .inc
file and I have other standard .inc files that I use to set up test renders with
grid lines, axes, lighting, and a camera for test purposes.  I run the tests so
they can complete quickly while I'm doing modeling.

BTW:  I have access to some really big linux servers with 64 cores.  I have a
rendering going on one of those machines, using up most of those cores, that has
been going since early July.  It's 88% done now...
