A medium shot, low-angle view depicts a regal queen seated upon a grand throne within the ruins of an underwater city. The queen is a woman with a mature figure and large, firm breasts accentuated by a tight corset that reveals deep cleavage. She possesses intelligent, narrow eyes and a unique "jellyfish" hairstyle, her expression reflecting a hidden sadness and empathy despite her royal status. She wears an elegant gown in a color palette of young grass green (#A3B18A) and cream (#FEFAE0), with dark green accents (#588157). She sits with an air of composed dignity, her right hand firmly gripping an ornate scepter resting against the throne's armrest, while her left hand rests gracefully on her lap. The background features the decaying grandeur of underwater ruins, with ancient stone pillars and crumbling arches overgrown with sea flora, all submerged in deep blue water. The lighting is ethereal and filtered from the surface, creating shimmering caustic patterns and a serene yet melancholic mood, with floating marine particles and a soft depth of field.
