Seamus, that OOC is a great image in itself and you can almost leave it as-is, or perhaps just crop it to square. You could add a little bit of life by increasing (slightly) contrast, clarity, vibrance (but keeping in check reds and oranges), sharpness, and maybe a little gentle post-crop vignetting. I'd like to keep the sense of bleakness, but not total desperation, if that makes sense.
