Modelling:
as usual everything looks very well modelled (ok except the phone, which
looks a bit too much like a superellipsoid). But I somehow feel the lack of
wires and cables everywhere. It would add so much to the realism. And where
is everybody at 8:25? :)
Texturing:
the wood looks very good IMO. I find the floor excellent too (I love how the
light bulbs reflect on it).
The only thing I would complain of is that some metallic textures look a bit
too *white*.
Lighting:
absolutely great! Absolutely photorealistic. The best thing here (and the
most important one).
Render time:
30 h for such a scene sounds really fast.

Lighting looks pretty good. Even with the temporary textures and models
it almost looks real, though I can see apots where I think you'll try to
make improvements...

Ah! That's it! It must be imperceptible. It is acting here like aa, but
softer, altought it need many samples... :(

Yes, bad quick-modelling: must be corrected.

Cables are the next thing to add. And, FYI, it is 8:25 P.M.! All workers
are at home, but someone left the lights turned on. I'm planning some funny
storytelling here... :)

Yes, I used a dummy texture too clear. Corrected for the next WIP.
Thanks!

Well this discussion is completely over my head, but looks good anyway!
Wish MY office was so neat. . .

On a floor like that I bet you could go really fast on a
wheeley chair.

The only thing that says 'raytrace' to me in the scene are the
completely straight-line wood textures on the bookshelf and desktop.
They need turbulence.

You know, it took me over 30 seconds to realize that was
*not* a photo. The phone gave it away. *Very* realistic
image!
