A photorealistic street art mural of a massive green anaconda emerging from the murky flooded floor of an abandoned zoo reptile house, its diamond-patterned scales rendered in hyperrealistic spray paint with wet sheen and muscular coils, misty blue hour light streaming through shattered glass dome ceiling casting ethereal fog across the water, mood prehistoric and primal yet melancholic, composition centered with snake's powerful body rising through debris, scattered broken terrariums and toppled feed bins creating zoo decay, color palette deep jungle greens and midnight blacks contrasted with warm amber mist and soft steel gray reflections
