Negative Space
1) Negative space is the area around the main point of an image, it is the space around an object.
2) I found negative space around the subject and the subject itself. Half of my cutout the pink was the subject and the other half the pink was the surrounding area of the subject.
3) It helps define boundaries to see the shapes you are drawing. It will make a silhouette of the main point.
4) Negative space does enhance the drawing because it it makes your eye concentrate more on the drawing because you try to find the subject.
