Thanks Bryan.

Couple things I noticed:

"intervals 10". The default media method adjusts intervals itself, unless 
you really want to change it anyhow. Could be slowing the render down.

"assumed_gamma 0.8". That would explain the washed out appearance since 1.0 
is usually recommended. Although, that's not much different.

I shortened the fade_distance to half, or 1.5, then raised the color up to 
3.0 for those wall lights and the tunnel is much darker; also with the 
assumed_gamma at 1. Raised the media scattering color up to 0.0025, as well, 
so it's smokier. Smokey might not be your idea for this scene but it sure is 
more visible.

The main thing is apparently those lights, though. Really makes a difference 
changing those.

You might find it necessary to increase the media samples some to prevent 
choppiness of the media, especially since it's going through that grid.

Bob
