Anamorphic Drawing

Before I go into explaining my anamorphic drawing; I want to first say that I never claimed to be skilled with a pencil and paper. That being said, here is what came of my fumbling. Clearly, it took me a couple of tries to get the idea correctly executed. first I attempted a pyramid with the use of the pencil to help create depth. Then I decided on focusing on the good ol' fashioned basics and try to finish a cube.
