Most of these keyframe illustrations served as look-and-feel style guides for the VFX department. These were painted "matte-painting style" over Art Department model assets, often with much additional detailing added in 2-D. The main goal was to convey lighting, mood and atmosphere. Again, many artists contributed to the design, under the direction of Production Designer Darren Gilford and VFX Art Director Ben Proctor (who did much of the initial design work,) David Levy, Daniel Simon and set designers Ben Edelberg, Joe Hiura and Rob Johnson.
