THE NATIVITY,DETALJ , NG WASHINGTON Petrus Christus (1410-1476)

The picture has something of this: window, light, abstract, sky, landscape, snow, tree, texture, water, house, bridge, winter, nature, architecture, weather, shadow.
Perhaps it’s a painting of a person sitting on a bench looking out a window at a bird flying in the sky over a body of water with a tree in the foreground.
