I was drawing the train tracks from one of my photos. I noticed that due to the strong perspective of the photos the drawing became a long triangle shape that started with the vanishing point and stretched out with the tracks to the edge of the page. This got me thinking that if I do a few of these drawings I can put them next to each other like slices of pizza so each drawing shares the same vanishing point in the middle. These pieces can build next to each other until a whole circle is formed. This idea partly came about when I was looking at the space around my drawing and wondering how I could fill it.
