WANDERING EARTH - Surface Elevator

What if Earth itself was the spaceship to save humanity?

(Those drawings were made on paper and then shaded in Photoshop)
This was the first drawing we made for the movie Wandering Earth. At the time the project was still in pitch so this picture was made to convince investors that we knew what a Chinese sci-fi movie could look like. This elevator is designed to take people from the underground cities up to the surface, a travel of more than 2km. So the elevator was made to offer some comfort, hot water and vending machine for snacks. But due to the scarcity of ressources, finish panels are reduced to the minimum and the mechanical parts are taking over the space.
