I always think IR alone is not what makes the picture as it were -it can only enhance, or detract attention from, an existing image. Following this train of thought the first and last images in the posted series work well, in particular the last one and would perhaps be even better if the persons were allowed to get a little closer.
The sight of those moats makes me wonder how the cellar smells - pretty mouldy I guess. So a fit place for a life-sentenced prisoner or even ghosts.
