Really good I love the Noir detective feel good job 
This is totally cool. My only criticism is that some of the cast shadows, especially the big one cast by the chair, seem to be going in the wrong direction. But I could be wrong; cast shadows do weird things.
Someone below mentioned having the light cast by a car driving past. They're right - that would make a cool animation, but trying to animate this scene with a moving light source makes me twitchy just thinking about it.
That looks rather cool.
To work with light is difficult, but light and animation, looking so great together, is wonderful!!
Brilliant work jalonso. Sam Spade would fit right in.
I hope you keep up your amazing clip with these Joint rooms. I look forward to every new addition. 
philip marlowe's office? the light effect is very....ah cinematic !
