Modeled, posed and rendered in Carrara.
The octagonal 'tunnel' was built from Carrara primitives and spline objects, and was originally intended for a slightly different project. I then re-textured it using some 'seamless' textures from Renderosity, which gave the scene its own distinctive, rather grim appearance.
The scene is lit by three small bulb lights, two of which are visible in the scene.
I probably need to get away from the 'figure walks down a somber corridor' scene now, as the theme is starting to feel a little worn-out ...
