“The important features of human figures, aside from their disposition, are: proportion, size and attitude.”
It’s interesting to note that when the focus of the drawing is the building, it is difficult to know that it will be part of an academic community. However, when the physical space shares the drawing with numerous figures in groups and alone, there are elements about the drawings that immediately convey that these are college campuses. Professors smoking pipes, groups of college-age youth sporting backpacks, carrying books, playing guitars, or wearing “letter sweaters,” are some of the illuminating details that renderers use. The inclusion of pets and particular body language imply domesticity and peaceful or educational uses of the shared space.
