攝影主題：暖陽下的清新隨興肖像 人物與神態： 一位擁有烏黑長髮的年輕女性，左手輕扶髮絲，髮絲隨風輕拂臉龐。她展現燦爛自信的笑容，露出潔白牙齒，眼神明亮，散發青春活力的感染力，動作俏皮可愛。 服裝細節： 上衣： 米白色寬鬆針織毛衣，材質柔軟。右肩自然滑落（露肩設計），展現優美的鎖骨線條；短版剪裁露出平坦腹部與肚臍。 下裝： 復古洗色藍色牛仔褲，細節可見鈕扣與部分拉鍊。 配飾： 左肩背著米色帆布環保袋，袋面上印有「Made in Kowloon」等深色文藝感字樣。 場景與構圖： 戶外環境（如公園或林蔭道），背景呈現柔焦效果，可見模糊的綠意樹葉與遠處人影。主體居中，背景的虛化使人物極致突出。 光線與氛圍： 採用自然光攝影，陽光從右上方灑落，於頭髮、肩膀與衣物纖維上形成鮮明的光影對比。整體呈現溫暖的米、藍、綠色調，畫質達 4K 寫實等級，光影層次豐富，營造出輕鬆愉悅的高級攝影感 Aesthetic cozy mirror selfie of a young man sitting casually on a chair, wearing a dark oversized hoodie and blue jeans, holding a professional camera in one hand, resting her face on the other hand with a soft dreamy smile. Warm beige indoor background with soft studio lighting, minimal modern interior. Cute cartoon-style doodles around her including a smiling sunflower character and hand-drawn yellow sun, playful white sketch lines around the camera. Handwritten romantic Ultra-realistic cinematic photograph, 9:16 vertical. Use my uploaded female subject as the ONLY face reference — her face, bone structure, proportions, and identity must remain 100% accurate. She is sitting low and relaxed on a worn vintage couch inside a messy 90s-era bedroom, dripping with grunge attitude and self-confidence. The entire room tells a story of obsession — the walls are completely covered in posters, photos, magazine clippings, and polaroids of HER, all different versions of her: glam looks, grungy looks, party looks, soft looks, edgy looks, all chaotic and layered, taped and pinned unevenly like a shrine to herself. Wardrobe: She wears an oversized, slouchy dark hoodie left open, revealing a white tube top underneath. The outfit is provocative but raw — lots of exposed skin at the waist, collarbones, shoulders, and legs. The vibe is unapologetically sexy, rebellious, and confident. Bare legs or very short bottoms, worn sneakers or socks, very lived-in 90s styling. Hair & makeup: Hair is messy, slightly undone, effortlessly sexy. Makeup is grungy-glam — smoky eyes, dark liner, slightly smudged, natural but seductive skin texture. No over-polish. Pose & expression: She sits back into the couch with dominant, careless confidence — legs apart or casually stretched, shoulders relaxed. Her expression is sultry, knowing, and powerful, like she’s fully aware the entire room revolves around her. She looks down toward the camera, owning the frame. Camera & composition: The camera is placed very low on the floor, angled sharply upward toward her, creating dramatic depth perception. Her legs and body feel larger in the foreground, her face looming above, while the poster-covered walls stretch upward behind her, creating a warped, immersive perspective. Slight wide-angle distortion for intensity. Lighting: Moody, low-light bedroom lighting — a mix of cool blue tones and dirty warm highlights. Neon or lamp glow spills across the posters. Shadows fall unevenly across the room, adding grit and texture. Film grain, subtle motion blur energy, raw 90s music-video atmosphere. Overall vibe: Sexy, grungy, chaotic, self-obsessed
