There seems to be some inconsistency in how the right-hand wall meets the
ceiling at the corners. It looks like there are some small holes in the
ceiling right at the intersection. Similarly, there's a small black streak
in the bottom right-hand corner of the image.

I also find the shadows a bit confusing in places, causing me to wonder
where all the light is coming from. The overall impression is quite
pleasing, but when I look at the light patterns on the ceiling, it just
looks a bit wrong. It's hard to describe, but the pattern of lighter/darker
areas along the left-hand wall and ceiling seam don't feel right.

As another person pointed out, the window frame needs to be lit. I would
recommend a large, brightly ambient plane to the left of the image. That
would have the added benefit of lighting the robots slightly more and
possibly cleaning up the shadows on the ceiling at the same time that it
lights up the window frame.

Overall, it's a very nice looking image. Very good modelling work.

Dan,

Thanks for the comments. Your ambient plane idea did the trick!

Thanks,
Sean

AFAIK This often happens when quality of one radiosity setting is too high 
while other is to low, in example with good count and bad error_bound, or 
vice-versa. 

Second problem might be that light source is too small, then either 
increase count very high (along with lower error_bound bound not too much, 
and higher nearest_count), and/or, as Stefan suggested - add ambient light 
source - object, or small shadowless light.
