It looks really good, just i think the smoke looks fairly bright.
Furthermore the shadowed parts of the wood on the left look much brighter
than the left side of the book for example.  Probably reducing the ambient
would help.

As 'Is' mentioned, the table looks to clan apart from the 'writings'. 
Some more (previously made) burns from the iron and some scratches would
look nice.

I had a look at the small radiosity version and it looks fairly natural
(as far as i can see at that size)  You should expect a yellow tint with
all the wood.  The other walls of the room are important too of course,
furthermore you an vary the light source color. 

And of course don't forget to turn all ambient finishes to 0 (apart from
the lamp)

Thank you, but I think there is still too empty space.

Yeah, you're probably right.

I'll try to fix the handle of the screwdriver. As concern the soldering iron
and the screen you could suggest me what is wrong. ;)

As a matter of fact, I decided to start this scene on May the 25th. As
concern the spider, it took me the first week of May to model it, just at
the beginning of the round, but I couldn't get any good idea on how using it
until the end of the month.

It's just my second entry, I don't expect that much. Thank you anyway.

Well, to say the truth, I'd want you to know that the spider has been built.
If the scene doesn't show this, well, there's lack of something...

I tried to model a small circuit board, but I didn't get any good result.
Probably I need to find some photos or drawings to use as reference. BTW
I'll try to add smaller screws, screwdrivers et similia.

I didn't notice it before you told me, but doesn't this happen in real life?
IMHO the shadow shouldn't darken the PC screen since it's emitting light. I
may be wrong.

> Still a fantastic picture...

Thank you a lot.

Dunno... maybe the sandwich is too small. Many people in my family told me
that the glass was too small (in the very first versions of the scene), so I
scale it up.
What do you all mean by dirt?: another texture layer or something more
material?

This is due to the dirty layer, as I mentioned in the main post. All
textures have ambient set to 0. The lamp is an emitting media, so the only
textures which don't have ambient 0 are the PC screen and the fluorescent
fingers of the clock.

I'll post a larger image to show how odd these yellow tones look.

Yeah, I have really not many fonts...
I'll search in the net.
Thank you anyway.

I rendered a bigger version. This time I commented out some include files
and the yellow tones disappeared (as you can see).
So, the gulty is not the wood texture, but something among:
spider,
spider legs,
piece of paper,
sphere sweeps,
sandwich,
glass of water.
I'll start to add one by one these objects, and when the yellow tones come
back I'll discover what causes them.
Any stake?

Anyway, do you think that radiosity is a better choice than fill light?
The scene looks a bit too reddish: should I increase the grey_threshold?
Can you suggest me any good radiosity settings? High quality but not too
slow rendering (oximorous?) would be great (this one uses a humble 50-count
radiosity setting and took 29 minutes to render).

JRG.

We have a winner! aehm...
The guilty was the wire of the soldering iron. (I simply add it to the last
scene).
It's rather strange, isn't it?
Now the question is: is this a radiosity bug or a sphere_sweep bug?
How can I get rid of this? Who knows? Who am I to make these questions?
Does God exist? Is this yellow tone a divine manifestation? Will the
Universe collapse?
Will POV 3.5 be ready before I'm eighty?
