Modelling a tube train in Quill

Continuation of modelling in Quill. Experimenting and testing how much of the tube train I want to create. I like the idea of gaps, and pieces left to the imagination. Drawing upon my theatrical training at Wimbledon, where I am drawing attention to the elements that are important and creating impressions with light and form. The viewer can fill in the blanks. I like the similarity and metaphor relating to sight-loss and the brain filling in the blank spaces.
