Much better!
Although the right animal's left forefoot still looks like it's floating; it
doesn't show enough ambient occlusion. This suggests to me, "error_bound is too
high." Lowering it would add to the render time, but without the high
turbulence on the sand, you might be able to forgo the radiosity normal on.

Indeed!

I cannot see that it's floating, but may be I'm just to blind for that having
only 50% eyesight. The problem may be the belly indeed. Smaller lizzards are
dragging it over the ground but your ones are more comparable to komodo dragons
which did not (all the time). So I think we should stop nitpicking and simply
admire Thomas's wonderful work.
Best regards,
Michael

Presently, my error_bound is 1.0 which might indeed still be a bit too
high. However, what is visible is the back part of the paw which is not
completely on the ground. The fore part is hidden by the rock.
Indeed Michael, this /is/ a Komodo dragon :-) Totally anachronistic but
who cares? The image is not intended to be published in Nature. There
are Permian animal models to be bought on the web at ContentParadise,
but I find it a bit silly to buy a model just for one image, even if the
price is affordable.
As far as belly dragging is concerned, reptiles lift their belly when
active, even crocodiles do. The reptiles from the Permian are often
pictured in an erect pose (Lystrosaurus, Moschops for instance); see
http://www.youtube.com/watch?v=AHJDejFGDwk. I am not too sure if that is
their most common pose considering their anatomy, but there it is.

I have only seen a Komodo dragon once and this one looks too happy. o_O
From what I was told by its keeper. They are really bad tempered and
show it. Yours looks quite amicable. :-)

Not I, for one.

They may somewhat less bad tempered when among themselves, and who know,
those two may be in the middle of courtship....

ROFL You made my day Stephen. But why deny happiness to those poor
creatures? ;-)
This makes me think about how we humans unconsciously (and erroneously)
project on animals our own attitudes. The /smiling/ chimp is a good example.

Indeed. Never trust a chimp that shows its teeth. (Unless it's only the
upper ones, that is.)
Cats and smiles is an interesting story, too. Did you know that cats
actually "smile" at each other by closing their eyes?
