Here is my Truck Shading assignment submission.

Bedroom Assignment (Night/Day)
For Day: I used a light blue area pointing into the window. I also added a low power light orange area light inside room aimed at the bed.
For Night: I used a low power mid-blue area light outside the window to simulate a moonlight effect. There is also a similar area light inside the room near where the camera is located. The two lamps are light orange point lights inside the lamps. I initially created the lights in the center of the lamp, which did not look right, then realized that the lights were inside the stem of the lamp. Once I moved them forward I was able to achieve the lamp like effect.
