Contour shoe drawing

I created this artwork by putting a shoe on the table and drawing it in perpective. I drew one part at a time so I wouldn't get confused on which strap goes where. I measured the length and width of the shoe by using my pencil and eyeing it. I used a pencil, an eraser, my Chaco, and a lot of perserverance. I think my drawing definetely has contrast because of the smooth sides and the straight edges of the straps. It is also emphasized because it is isolated. In this lesson, I learned that even if I am frustrated, I have to keep going in order to learn how to fix what I am doing wrong.
