A photorealistic street art mural of a massive dragon with iridescent emerald and midnight blue scales slithering through the gutted turbine hall of an abandoned power plant, its serpentine body rendered in hyperrealistic spray paint with individual scale textures and molten gold eyes glowing in darkness, cold blue electric light from shattered control panels casting eerie glow across rusted metal framework, mood ancient and powerful yet ominous, composition dynamic with dragon coiling around giant industrial turbines filling the mechanical space, scattered broken generators and toppled concrete barriers creating industrial decay, color palette deep emerald greens and midnight blues contrasted with warm molten gold and cold electric blue light
