Transition from Sally's world to David's - Line to negative space
Sketch design - 3D virtual storyboarding the transition between David and Sally's worlds....positive space represented just with line, to David's casting capturing negative space.... Subtle transition using thicker lines from outlines to fill (line to negative space) and using the transition of the orange outlines representing Sally's work to a mist of orange over the negative shapes of commuters. Transition to white, to create a stark contrast between negative and positive shapes.
