Realistic Beach Vacation Snapshot

4:5 vertical, realistic beach vacation phone snapshot, like a friend's casual Xiaohongshu / Instagram vacation snapshot, not a professional studio shot. A clearly adult young East Asian woman, round soft egg-shaped face, full cheeks, bright almond eyes, small nose and lips, with a bit of natural asymmetry, eyes slightly squinting when smiling, overall cute, lively, and full of life. Dark brown long hair blown by the sea breeze, a few strands of hair sticking to her face; sheer peach-pink makeup, natural semi-matte skin, retaining slight pores, fine fuzz and real skin tone variations, not a perfect doll face. She wears a fresh, realistic light sea-blue and cream-white check two-piece swimsuit, natural cut, not overly revealing; just walked up from the shallow water, body and shoulders facing the same direction, one hand gently holding down a straw hat fluttering in the wind, the other holding sandals, laughing naturally while walking, not posing stiffly. The foreground is blurred waves and sunlit light-colored sand, the subject at the water's edge, background is blue-green sea, distant blurred beach umbrellas and a few vacationing figures. Slightly tilted composition, subject not perfectly centered, like a friend pressing the shutter without adjusting the frame; retaining slight hand-held shake, motion blur at edges, occasional missed focus and restrained phone compression artifacts, but the face is still clearly discernible. Late afternoon sunlight comes from behind the side, falling on hair strands, cheek edges, shoulders and sea spray, forming a natural warm gold rim light; the cold blue ambient light reflected from the sea gently fills the facial shadows. Forehead and cheeks maintain soft diffuse reflections, nose bridge only retains a restrained narrow highlight; the wet sheen from just leaving the sea appears only on hair ends, shoulders and arms, not making the whole face oily. Slight natural overexposure allowed in highlights, overall like a real summer travel photo, not a meticulously crafted photography sample. Add artistic handwritten text 'nuyoah' in the lower right corner as a signature. No text other than the signature. Avoid: plastic skin, influencer filter face, over-smoothing, over-sharpening, HDR, complex dramatic lighting, professional studio feel, exaggerated body proportions, deliberate sexy poses, stiff posing, looking back with neck twisted, oily face, swimsuit structural errors, deformed fingers, extra limbs, duplicate people.
