The curving stones provide a lead-in to the main building with the figure on the thirds to add interest.
Many photography books cover composition but this goes into much more depth than many of the more general books. The information here is not just the dreaded "rule of thirds" or "stick a rock in the foreground of your wide angle landscape shots", its much more detailed than that.
It covers using shapes and contrasts, the effect of colours and intent, plus a whole host more.
I would recommend reading it in one pass to get a feel for it. Then going back and studying a small section and attempt to use it in making your pictures.
A rusty gasometer lit by a setting sun makes for an interesting abstract. Tilting the camera utilises the rectangular frame to gives a composition made almost entirely of simple geometric shapes.
All in all a highly recommended book.
