We need to start with the square shapes and then we will round them up. As you hit the vanishing points think creatively what you are going to draw. Block objects with lose lines in perspective.
What we are going to do next is to use is to work with a different color pencil in that way we will be able to choose whichever lines we want to work with.
When drawing a circle in perspective, start with a rectangle, draw two diagonal lines to find the center and then start drawing the circle in perspective.
