Part 2 drawing....positive and negative space project 1.EXERCISE 1

This is a project using positive and negative space. I have used some work by the artist Escher whom liked to play with positive and negative space. 

Here i have found online 2 examples using positive and negative space

 If you focus on the white, you see a vase as the positive space and the black surrounding it as the negative.  If you concentrate on the black, you will see two faces as the positive space (the main focus), and the white space becomes the negative space in-between or surrounding the faces.
In the second picture, the orange vase is the positive space, since it is the main focus.  The light area surrounding the vase is the negative space. In the second picture, the area which appears as positive or negative depends on where you focus.
