Also,
about the image, The plant adds a lot, wouldn't it be even nicer with more
backside diffuse (translucency) or even double_illuminate?

For the flower pot, temporarily switching media off and tweaking the brilliance
so that light bleeds a little deeper into shaded parts could make a quite
realistic terra cotta.

Is the downards light over the statue excluded from media? this looks a little
odd compared to the light entering the room which has a lot.

All good points, that I'll try to work into the final version ... just 
wanted to get the docs squared away 1st ... business before pleasure right!

Yup. For area lights, I typically use half the area light's size as 
fade_distance; for point lights I pick some distance that might be a 
reasonable radius of the light source (e.g. radius of a light bulb).

Here's another version after playing around with the lighting and 
composition.

Getting better and better.
Maybe a little more "normal" in the floor reflection. Not too much though.
