I love panoramic compositions and I also love Mono. The tonality in this is very good. I have to agree with Fergusb that the horizon is a bit off. Sort that out Rafago and you’ve got a great image. This place is called Mussenden Temple, built by the Bishop of Derry as a library for his lady friend. (Maybe his wife, I don’t know.) A room with a view. I can’t remember names or dates concerning it, but a quick Google will turn up all the relevant info.
