Landscape in Luxemburg castle Fels Barend Cornelis Koekkoek (1803-1862)

The picture has something of this: fog, landscape, nature, mountain, tree, sky, sunset, outdoors, mist, dawn, wood, fall, water, hill, light, sun, evening, river.
Perhaps it’s a painting of a landscape with a castle on a hill in the distance and people walking on a path in the foreground, with a cloudy sky in the background.
