3DLighting: Lighting bedroom- W.I.P

Lighting a bedroom scene

My main, current idea for this bedroom is to create a room where a college music student has been up all night trying meet his deadline extension. He had to compose some sheet music, so stayed up all night trying to complete it. There are strewn, screwed up pieces of paper with failed writing attempts littered around, particularly around the bin, where he has missed! There are also piece of music that haven't been screwed up littered on the bed and surrounding floor. There 3/4 full bottle of wine on his bedside table, empty wine glass kicked over on the floor.

The lamp next to his bed is still turned on, bringing attention to the music books and clock on his bedside table. Other objects include an ashtray with many smoked cigarettes but one half smoked. I want to give the audience the impressed he has rushed out of his bedroom in order to meet his deadline

Lighting

I want the time of day to be an early winter morning, in the northern hemisphere. I want there to be an orange hue to the light streaming in through the window. I want there to be a dusty/ smoke residue atmosphere and will use Arnold atmospheric volume to create this. This will enable me to create 'god rays' through the blinds which will help to suggest dust/smoke particles in the air.

1 - Simple skydome setup, with a distance light for the sun for the sunlight streaming in through windows - there are also quad portal lights outside the windows to help reduce the noise and help guide the skydome light sampling through the windows. Added some textures to wall and floor from substance Source.

2 - Added some extra lights to enable me to create the sun beams/god rays through the blinds. Tweaked the lighting setup and added 2 spot light outside of the two windows, I found I wasn't getting the results I wanted by just using the distance light. By adding the two spot lights, together with the distance light, I could have the beams and sunlight working together. I just had to make sure they were all pointing in the same direction so not to break the illusion.
I also added colour to the other wall and some textures on the posters.
What I want to do now, is change the hue of the light to an orange colour.
