Viewing light levels

This exercise is about finding good examples of light levels changing radically within a scene and explaining how these changes are justified. On reflection, it has to be said that I consider this task as one of the easiest so far. I struggled to compose the shots of creating depth with lighting. This is true. However, after having experienced with that, it's quite clear to me the use of sources of light. So, according to this and applying the rule that warm light means comfort and cold light the opposite, I'd like to expose the following stills:

Picture 1: This first example shows a man in his living room. The light is warm as this is a space where he feels good. The problem is that the place is connected to another room through a door. And in this room is happening something that is not convenient for the man. Thus, when opening the door his relaxation is gone. And we can see clearly the contrast between the two atmospheres. The first one has a light which is warm and pleasant. On the other hand, the second one, has a very cold light. Obviously, the character is not happy at all after the quiet environment is brought into disruption.   

Picture 2: In this case, there's an action that causes the change. There's no two different scenarios. Just a lamp that has been switched off after being thrown on to the floor. This motivates going from a nice lighting to total darkness. And the variation reflects well the mood of the protagonist. Before, he was thoughtful - although he was angry too. Afterwards, he is very mad at something and it all goes black because  of that.
