The world of Escher representation

This is a representation of what I intent to do with the video game. I want to create an atmosphere of lost and disorientation, where the player have to find his way out (like a puzzle).

I made this 3D model with Rhino, so I created a grid of curves that were extruded to make them interlock. Then I added stairs in different orientations to create the feeling of being lost. The spheres are there to provide the player with a landmark to inform him his location. After that, I rendered it with simple plastic material, and in photoshop, I added people and made it into a sepia color.
