So there's mystery, shape & form, point-of-view, receding space, and many other attractions to a subject. This ghost house has many. This particular shot also imposes on the viewer. Shooting from underneath and upward as well as being fairly wide, causes the subject to loom at us. It's even more effective in this case because it is such compelling architecture and that curved glass encases the rags that once was a curtain. It's spooky. But it also begs the questions: "What's going on here? Is this old mansion occupied? Is there someone or something in there?". So point-of-view becomes more important with a subject like this.
And the form snapped into place in the frame which I like.
