Oh no. Were they moving in the wind? That’s so scary

The woman in the bottom right has a very weird arm posture and the seperating lines in the windows are too glossy for cast iron. They’d either need to be wood which I doubt for a stained glass window or polished metal which I’ve never seen before. The window also seems more lit up than the rest of the room. Also the foreground (white flowers in the bottom right) and the window seem to be in focus which is impossible.
