Its very late I am posting my contribution for this great lighting challenge, but I am quite satisfied with my Render.
The lighting has been tweaked in 3D-Max, this scene light up with One Direct lighting which is my main source light from out side & Environment light as my skylight.
I have used two more lights to make this scene more dramatic, Spotlight & VRayLight sphere.
I wanted to give some moisture fell in this render; I hope I could manage to give the same look as I thought of.
I have also used Photoshop for little brightness & color corrections.
Anyways this scene took my three days for all the textures, some modeling correction and VRay settings.
I would like to have your expert C&C
It has been great practice of lighting and texturing for my very first VRay output.
