B: In my cut out I found the negative space in everything I didn't cut out. So the construction paper that never got cut, was on the left side positive space and on the left side negative. In the sketch above, the negative space was pretty much everything sketched and scribbled around the objects. But the white spaces, the object outlines, were the positive spaces.
C. Seeing negative space as an artist really helps the artist draw a more accurate and precise drawing of the object they are drawing because they not only take in mind what the object in and what are the details on the object but also the details around the object.
D. Yes. As I said in part C it really helps because, let's say, you are drawing a cup. You think of a regular glass cup as a cylinder. But if you take into account the things around the cup it might actually seem like a basic cylinder to you. It will then become a more detailed "cylinder" or in this case, a more detailed cup or a more ACCURATE AND PRECISE cup.
