Hey Thomas, this is quite an interesting series you're working on!
I'm wondering, does that ejecta seem a bit too grainy? I know there are bound to
be larger chunks of earth thrown high from such a large impact, though I'm
pretty sure the majority of particles would be tiny enough to appear as dust
from that distance.
Also, is this near the beginning of the LHB? If not, you might want to pock up
the crust a bit with craters, and dirty up the sky with pulverized earth. Here
are a couple reference photos of large dust clouds that you might find useful:

A gigantic meteoroid illuminating a dust cloud would be a very dramatic sight :)
(It's too bad nobody has developed a 3D fluid simulator that also exports to a
POV-Ray df3 file. We've got a bunch of POVvers around here who are also talented
programmers... we need more utilities! :D )
