A photorealistic street art mural of a massive mechanical stag beetle with iridescent copper carapace and glowing amber eyes crawling across the crumbling brick wall of an abandoned parking structure, its segmented body rendered in hyperrealistic spray paint with intricate gear mechanisms and brass rivets visible, warm sunset light streaming through shattered concrete pillars casting golden beams across oil-stained floors, mood futuristic and industrial yet organic, composition dynamic with beetle mid-crawl filling the angular space, scattered broken vehicles and toppled traffic cones creating urban decay, color palette warm coppers and bronzes contrasted with cool concrete grays and soft amber sunset glow
