Refraction

This illustration presented me with two different challenges, geometry and white space.
The lines in the window, room and light needed to stay crisp and clean in order to read well once they were finished. To do this I measured everything out in pencil beforehand. The first lines were drawn in friskit to preserve the white of the page. The second were the lines in the window, so I wouldn't lose the light pencil I'd painstakingly measured out.
The piece was built in slow layers of friskit and ink, covering and uncovering select layers to build shadow and light. However, some of my friskit application was a bit sloppy which resulted in mottled patches of ink in places I needed the image to be stark white. To solve this I went back over the lightest portions of the illustration with white gouache. While this worked well and helped me meet my deadline my goal in the future is to apply the friskit thick and evenly enough to avoid this.
