"Create a hyper-realistic 8K lifestyle photograph in a vertical 3:4 aspect ratio.
Subject: A young adult woman with fair to light-medium skin and short blue-black bob-cut hair. She has a soft closed-lip smile and looks directly at the camera. She wears natural makeup with rosy lips and well-defined eyebrows. Her physique is athletic with naturally curvy proportions and realistic skin texture. She wears a thin silver bracelet on her right wrist.
Outfit: A classic brown and black leopard-print triangle bikini. The top features thin black strings crossing over the upper chest. She wears a beige straw cowboy hat with wide brims slightly curved upward and a black hat string hanging loosely, framing her face and neck.
Pose & Framing: Medium-long portrait framed from the knees up at eye level. Slight contrapposto stance. Her right arm is raised, fingers gently touching the front brim of the hat. Her left arm falls naturally by her side.
Lighting: Bright natural midday sunlight with strong directional light. Defined shadows under the hat and along the neck and torso. Subtle luminous highlights on the skin and sand.
Environment: Tropical beach with light sand under a vibrant blue sky. Slight depth of field keeps the woman in sharp focus while softly blurring the background. The scenery includes ocean waves with white foam, twin mountain peaks on the left side, and a distant coastal city skyline stretching along the right side of the beach.
Mood & Color Palette: Vibrant summer vacation atmosphere. Dominant tones of light blue, beige, bronze, black, brown, and warm natural skin tones."
