You are right, I didn't use any sophisticated method for the fur - only the
displacement tool of Poseray.
Far from perfect, it works at the face, but not equally good at the back - I
should have worked a bit on the bump_map used for displacement.

And - of course you were allowed to publish the image on facebook :-)

Thanks !
Would'nt the result be better with HGPovray displacement then? (thought I never
managed to compile it myself, were you on Windows?)

Wait... That cat wasn't in the picture, where is he hidden? :-)

Outstanding, as usual !
Surely the cat fur could be improved, and the reuse of the large leaves on the
top right is a bit too obvious. But even said that, the whole picture is so
pleasant to the eye (especially here where it's a depressing dark rainy day ;-)
)

Good, as always!

I have a couple of comments though, if you don't mind, as I am not 
entirely happy with the scene.

The wooden frames of the windows, while obviously in shadow, are too 
bright imo, or seem over-exposed somehow. I guess that the contrast 
outside (over-exposed) / inside (right exposure, but just) is to be 
blamed here. I think that I would have made the scene a tiny bit darker, 
with the consequence of over-exposing the outside even more of course. 
Difficult choice.

As mentioned, the fur. displacement mapping in Poseray, as you mentioned 
in another post, is a good alternative indeed to the outstanding 
Blender. I have played with it a bit but not enough till now. Another 
entry on the ToDo list; you seem to provide me with a substantial amount 
of them it appears :-)

Agreed, but only very slightly, because, average viewer is now getting used to
see subjectively tone mapped High dynamic range / bracketed photographs,  such
as the ones from Matthieu Ricard. So keeping a little bit of this "excessive"
range in is an important part of the wow effect at work here. Kind of like what
happens when one snaps the tracked motion of a shaky hand held camera onto a 3d
rendered animation, it's theoretically less professional/studio looking camera
works, but it actually increases the viewer's willing suspension of disbelief
(and it also works on pure live action such as Blair Witch or Dancer in the
dark)
Digression is getting too far, but the point being HDR has now become mainstream
and can be used as one of the many tricks to disguise hand knitted CG into what
looks like a more spontaneous picture.

Norbert Kern, you did receive David Bucks personal congratulations for your
picture over at "Persistence of Vision... Forever" public Facebook group :-)

I do agree with you of course. However, I have a gut feeling that 
something else is at play here. Possibly involving the slight 
reflectivity mentioned by Norbert, or something involving a high 
"ambient" value (?). Look also at the left-hand chair: It should be in 
shadow (light coming from left rear) but it is strongly illuminated by a 
light from under the table... Is that reflection from the table cloth? 
It seems too bright to me.

But those are just nitpicking comments. The image is gorgeous nonetheless.

A peaceful and complex scene, with many interesting elements. The fur of 
the cats could be not perfect, but works, and also the poses are very 
nice, they seems really interested to the light and to the context.
I like it!

You know there are days when I despair of ever getting to this level.
Really great image - love it
