Prison of The Red Fog

The prison which served for torturing as many prisoners (somewhere after the corner, down in the labirinth) that its fog became red.
The rocks and the floor were initially block-modeled to get the rough forms and then sculpted using dyntopo.
The fog is created using Mist pass overlayed with procedural texture and a hand-painted mask.
Rendered, composited with Cycles. No external post-processing.
This is another personal project.
