Georgia's drawing exhibits bold, contrasting values and surface variations that makes the image "pop." Whereas Luke's drawing exhibits a more uniform approach to rendering the light patterns and atmosphere which creates a "cooler," more calming light. Of particular note is the difference in drawing the background and the way the negative space has been addressed.
Luke has invented a textural background with a negative area that emphasizes the still life moving upward. Georgia has focused on the table edge and ground plane moving downward.
