Jessenia’s photo had really strong perspective through the use of depth of field and angle. Although it was not advised to photograph cars, these feel like a fantastic alternative as they all variate in color, shape, and size. The depth of field plays into the perspective by being deep near the right of the image and shallow towards the left. The angle also serves the perspective by being low enough to capture the subjects but not low enough to have one overpower the others.
Remember that depth of field refers to focus. Deep space is created by perspective mostly the converging lines of what may be a monitor and the table. Diminishing scale also creates a sense of deep space.
