This drawing has no setting. I used pure contouring on this and made the lines clean and sharp. The most visible lines are dark and the less visible are light and shadowy.
I tried to make the shoes proportional and the same size as my actual shoe. This project started out with one angle of my shoe, and then ended with three. I shaded certain parts of the shoe, but had to erase them.
I wear the shoes portrayed in this piece at least once a week, they are one of my favorite shoes. I would change the frontal view of the shoes, and fix the size of the back of it.
