The last stage of the model composition will be lighting, if too direct, it will look staged and fake, not enough, it will look flat.  When designing the model I wanted the shape of the window outline as part of the lighting, casting bright patches on the carpet and walls and I had to be careful to block out other light sources that would cast alternative shadows.  The last stage for this project will be a small pencil drawing from a large photograph with enough content to build a narrative.
