"Generate an ultra-realistic portrait of a young woman with golden blonde hair that falls in soft, natural waves to her shoulders. Her eyes are vivid, crystal-clear blue, large and expressive, with long, defined eyelashes. She has smooth, flawless skin with a fair complexion and a subtle pink undertone, with visible pores for a hyper-realistic effect. Her facial structure is elegant: high cheekbones, a small, straight nose, and full, naturally pink lips. Her smile is warm and inviting, showing perfect white teeth. She is wearing a stylish bikini, featuring a simple yet elegant design, such as a solid color or a subtle pattern. The background is a serene beach setting with soft sand, a clear blue sky, and gentle waves in the distance. Use natural lighting to emphasize her features and the texture of her skin and hair, while creating a warm and inviting atmosphere. Her pose should be relaxed, exuding confidence and approachability. Hyper-realistic details should include individual strands of hair, natural skin textures, and realistic shadows cast by the sunlight.
