A photorealistic street art mural of a massive stag with enormous antlers standing in the gutted interior of an abandoned library, its chestnut fur rendered in hyperrealistic spray paint with individual strand textures and breath misting in cold air, golden afternoon light streaming through shattered skylights casting dramatic dust-mote beams across collapsed bookshelves, mood regal and melancholic yet peaceful, composition centered with stag's head and antlers filling the vertical space, scattered leather-bound books and toppled reading ladders creating intellectual decay, color palette warm chestnut browns and amber contrasted with cool stone grays and soft golden light
