Realistic Ocean Dreamlike Portrait

Create a dreamy underwater fantasy portrait showing a young woman from the mid-thigh up, in a deep teal ocean background with floating particles and soft mist. She has very long, flowing wavy hair floating weightlessly around her shoulders, with a coral-shaped hair accessory pinned on the right side of her head. She wears a delicate semi-transparent sleeveless slip dress with soft folds at the waist, the tulle fabric looking especially ethereal underwater. Her skin is fair and softly lit, her pose relaxed, arms hanging naturally. The composition is vertically centered, with painterly realism and a soft cinematic sheen. Add an opaque square blocking block over the entire face, colored , covering all facial features while keeping the hair and body visible. Use soft focus, low contrast, subtle glow, underwater diffuse reflection effects, creating an artistic fantasy photography atmosphere, no text, no extra objects.
