The entire scene looks a bit dark compared to the fact that is in being illuminated by daylight (Sunlight). Since you have approached the "Faked" GI lighting technique, the fill and bounce lights have to be notched a bit higher. The scene could also use contact shadows (Ambient Occlusion), which is possible only if you're using GI calculator solutions like Photon Mapping, Light Tracing or Radiosity, etc. However, you could also use the Mental Ray Ambient Occlusion Material and create a pass just for the contact shadow and then composite it with the main image.
Other than that, the champagne glasses are reflecting unnaturally, might wanna look into that and correct it accordingly.

In this scene, you have three primary light sources that would be casting shadows:

One soft light in the window (sky).

One hard light coming through the window (sun).

One soft light coming from the floor (bounce from where the sunlight hits the floor).


That means you need shadows from the sunlight, that you already have. You need some shadows creeping mostly horizontally along the walls from the light coming from the window, and some shadows creeping mostly vertically along the walls from the light coming from the bounce light.

The sun is fine. Just increase the intensity a bit.

For the bounce light, try adding a spotlight right underneath the sun's main hotspot on the floor. Give it very soft mapped shadows, and an angle so wide it covers the entire room. The colour should be quite warm, about the same as where the sun hits the floor. Set it to exclude the floor, so it doesn't cast a shadow. Give it a falloff, probably an inverse square one.

Do the same for the skylight. Put a spotlight in the window, with soft mapped shadows. The color should be quite blue. Give it an inverse square falloff, just like with the bounce light.

Kill the ambient light, and boost the gamma until you get more light.


This should give you the basic lighting for this scene, I think. You will probably need to add some ambient to it as well, and maybe a couple of extra lights here and there, and maybe ambient occlusion as well.
