Ashley's drawing above illustrates an exaggerated intensity in value which is very complementary to the surrealistic shadows and space. The shadows seam to reveal the true character or secret life of the objects.
Connor's drawing is a more objective rendering of the forms. The limited tonal range creates a calm and realistic sense of the space as if light were cast through a window. In addition, he has addressed the negative space with subtle atmospheric rendering defining the table surface and enveloping the objects.
