View through a window frame looking out onto a cityscape at dusk

View through a window frame looking out onto a cityscape at dusk. The sky is blue with some clouds. Two buildings are visible: one is a modern, multi-story building with a glass-paneled facade and a row of small windows. The other is a glass building with interior lights on. Bare tree branches are in front of the buildings. In the foreground, part of a curtain is visible. The picture is taken inside, looking out, during daylight. The buildings are in the city of London, United Kingdom, though specific details are not discernible from the image.
