A photorealistic street art mural of a massive anaconda snake coiled through the broken windows of an abandoned subway station entrance, its emerald and black scales rendered in hyperrealistic spray paint with wet skin sheen, amber eyes glowing from shadow, mist creeping along rusted tracks below, mood ancient and dangerous, composition spiraling upward with snake head at apex, shattered tile walls and scattered subway signs creating urban decay, color palette vivid greens and deep blacks contrasted with cool blue-gray station tiles and warm amber emergency lights
