For last few weekends I was trying to create most real render based on movie scene I saw (Door In The Floor)
here is movie scene
and here is my render
I know that I could do much more but uh…it’s time to say that’s it and move on 
Render time: about 6 h for vrmap and 9 for final render.
for this scene I used new color mapping (intensity exponential) becuase with other it was really hard to achieve this kind of light as in movie.
realy nice matching. The rendertime seam as way out of productionlimits 8)

good render. i think you just need to warm the lights up a little bit and get rid of the crisp edges.
Cool. Sun should be hotter - and need a fill light for the foreground.
What AA filter did you use? Maybe more fuzziness there too.
Why did this take 6 - 9 hours?

I used catmull-rom AA. It was really hard to get sun hotter because when I did it i got too much light bounce on next wall. 6 - 9 hours…well AA took this time because I had problems with those details in front.
