I'm not sure I understand What you mean. Do you mean a bounding box that
doesn't intersect the ghost? How will that affect her transparency?

Yes. I've tried an aa threshold of up to 0.001... everything else looks
great, but she's still speckled! I've tried media aa as well.

Annoyingly, these artifacts appear in her reflections too. Since I'm using
hardly any phong or specular highlights and relying on true reflections to
provide shiny finishes, this can affect almost any object! :-(

Two comment -

1) The colours in the lower left of the image pane are much more avid and
"one-dimensional": You have the very yellow chair, and red, green and blue
books.
The rest of the image however, has more toned down and neutral colours.
Personally, I find that the effect draws my eyes down into that corner
(which is probably not where you want them)

2) Is that a photograph she has picked up to look at? Rotate it slightly, it
almost looks like she is browsing her iPod playlist.

At 1st sight I thought you had used MegaPOV aoi, couldn't you use that 
instead of media?

I like the floor normal too. I looks like carpet to me. I think the girl is
fine, although perhaps some kind of diaphanous gown or something would be
good. Also... nipples? Not that it matters. I know she comes from DAZ
without.

I have to say I particularly like the texture on the green vase, it looks
very good to me.
