Negative Space

A) I think negative space helps artists identify the back ground from the foreground, and think of them as separate things instead of one picture.
B) 1. In the cutouts, the negative spaces color changed. 2. In the stool drawing i made the foreground positive and the background negative.
C) It helps because you can think of the drawing as two layers.
D) Yes, since it gives the artist a better understanding of foreground and background.
