Image 2: keyword procedural + multiple levels
I use keyword multiple levels because plaza not only has lots different people who come from the different nation but also various facilities and functions.
To combine this two keywords in the final drawing(figure4), I thought to create the different altitude dense architectures to show the idea of 'levels'. And then I put the sun on the side of the sky, so from morning to the afternoon when the sun move, the sunlight will generate a gradual change of light and shadow into the surface of buildings, which is 'procedural'. I use the pencil to show the gradual light change from dark to bright.
