This is a highly detailed, CGI artwork depicting a biopunk landscape where a massive leviathan glides through the haunting depths of an eerie underwater environment. Its slick, scaled body is enhanced with bio-engineered modifications, featuring metallic implants that shimmer in the faint light. Glowing fluorescent tubes run along its spine, illuminating the surrounding area with an otherworldly glow. Jagged fins slice through the water, while toxic gas vents release noxious clouds that swirl around the leviathan. Bioluminescent flora bloom nearby, casting an enchanting yet foreboding light in the murky waters, creating a stunning fusion of nature and biotechnology that evokes both awe and terror.
