Very interesting.
One thing that I've learned with images such as these is that sometimes, its best to hone-in or identify something that strikes you about the image and then post process to bring that particular characteristic.
ie. in this image I find the stressed metal could work and so I'd push for a distressed look.
And so just for fun, I tried a high structure(detail) look combined with a rather strong vignette effect to add a feeling of obscurity feeling to the scene. TO sort of make someone work to figure out what their looking at. - of course this is all just from my own perspective, and so take it with a grain of salt.
PS. please don't take offense to the edit, I assure you that my intentions are based entirely on sharing ideas with others.
Hope this helps.
