Underwater Gamer in Diving Helmet

Create a photorealistic vertical underwater fantasy portrait of a young woman wearing a vintage brass diving helmet with a clear spherical glass dome, seated in an ancient submerged ruin. Show every face clearly with natural, detailed facial features, covering the facial features while leaving the hair, helmet, neck, and outfit visible. She has medium-length dark brown hair visible inside the dome and wears a vivid {argument name="suit color" default="red"} tailored blazer and matching trousers over a white shirt, with dark shoulder straps and brass diving gear around the collar. She holds a black handheld game console horizontally with both hands as if excitedly playing underwater. The scene is bright, cinematic, and highly detailed: turquoise-blue ocean water, sunbeams from above, rising air bubbles, colorful coral reefs on both sides, small tropical fish, two orange clownfish in the lower left foreground, a translucent jellyfish in the mid-right background, an old treasure chest on the seafloor at left, and ancient stone columns and ruins in the rear left. Use realistic lighting, glossy reflections on the glass helmet, brass metal details, soft depth of field, vibrant reef colors, and a magical adventurous mood. Vertical 3:4 composition, centered subject from knees upward, no text, no watermark.
