The Monument/Spiral Staircase (probably a cliché, but hey)

My latest finished scene:

It was inspired by the Monument in London, which I visited on a school trip on Wednesday. I have tried to imagine what it might look like at night.

Modelling was fairly simple but the texturing was more difficult. Lighting was also fairly simple and there wasn’t much compositing. All done in Blender internal.

Constructive criticism is welcome!
