Picket in the Balkans. Around 1878 Vasily Vereshchagin (1842-1904)

The picture has something of this: nature, texture, tree, water, dirty, wood, abstract, leaf, frost, cold, reflection, rusty, artistic, splash, winter.
Perhaps it’s a painting of two people standing in the snow in front of a group of trees, one holding a rifle and the other looking at something in the distance.
