Create a painting in the style of 19th-century realism featuring a herd of wild boars making their way through a snow-covered forest. The composition should highlight the contrast between the dark, textured fur of the boars and the bright, untouched snow. The forest should consist of tall, bare trees with a hint of snow clinging to their branches. Capture the muted, cold tones of winter with subtle variations in the whites and grays of the snow and the browns and blacks of the trees and boars. Focus on creating a sense of depth and movement within the scene, with the boars positioned at varying distances from the viewer. The overall mood should be one of stark beauty and the resilience of nature in winter.
