After a second look I think that the shadow at the back is being
caused by the table, try moving it or rendering without it and 
see what happens.  I know you wouldn't think that it's the table
as it doesn't seem to be in a position where it would cast a
shadow, but strange things can happen.

Candles really don't put out that much light. The room should be much
dimmer, IMO.

 a few candles don't but that many certainly would!  try it yourself.
(kids, get your parents' permission before lighting that many candles
and make sure they supervise) :)

Nonsense. They'd light their immediate area pretty well, but the overall
illumination is much too bright. Inverse square and all that, you know.

I think I overdid the brightness slightly. Please note however that only
half of the candles in the scene are visible. (there are two rows to the
right of the
camera)

I think you have to up the recursion limit with a smaller error bound.

Absolutely. More Grimlike, please.

Such a large number of candles would still light the area pretty well. 
Diffuse lighting would also help. The lighting in this image seems about 
right to me.

I can't say about this particular building (object), but I can say that a
much higher, vaulted ceiling shows variations in shadowing. In real time you
can see shadows flicker just as the candles do. Therefore, I would think the
light should fade a tad as it approaches the ceiling, even here.

I always like Gail's work, of course! :)

I'm re rendering it with the brightness turned down and the recursion
turned up. I think it looks better dimmer.

Thank you.
