Mikayla's drawing (top) exhibits boldly defined block forms within a dramatically lit space. The dark background is especially well rendered illustrating a gradual blend into the lighter foreground.
Martin's drawing, in contrast, illustrates a sharp division of background and foreground. In addition, the background is vignetted around the still life creating an implied white border. The lighting is strong and high contrasting. His attention to the details of texture and contour is very illustrative.
