Layers are a great way to enhance photographs for a grungy look. I felt that this ossuary photograph required a little more sinister look. Three textures later in addition to some dodging and burning, I achieved what I was after. The pose of the person standing is another matter - not exactly what I had in mind but it works good enough.
The challenge in this scene was to try to retain some detail in the window and have the rest of the image still acceptably bright and detailed. I could have done that with multiple exposures (HDR) but these days, some of the DSLR cameras have pretty amazing dynamic range. This makes it easier to lift the shadows and preserve detail.
