Onlined / Finished the spot.  Created the Elevator effect from scratch (including the look of the Glass doors with color tint, thickness, and reflections, all in 2D).  Used still frames of cogs, pulleys, and other mechanical components and hand-animated them to mimic/fake their back and forth motion as the elevator begins to move and/or comes to a stop, and added motion blur for realism. Agency Art gave us the creative freedom so I went for a photoreal/grahpic design look.  Approved at first screening resulting in no late night dinners :)  All VFX work was performed in 2D/flame without the help of any 3D package or 3D elements.
