冬の川辺と缶ココア

29歳の架空の成人日本人女性。成人らしい可愛い顔を第一優先にした、縦3:4の自然なスマホ写真。曇天の冬の夕方、普通の川辺の階段に座り、無地の缶ココアを両手で自然に包んで、撮影する友達へ口を閉じた優しい笑顔を向ける。キャメルのダッフルコート、赤とグレーの控えめなチェックマフラー、濃色ストレートジーンズ、白スニーカーで全身を覆う。古めのスマホ背面カメラ、約35mm相当。友達が立った高さから膝下〜頭を少し不完全に収める。空の一部だけを白飛びさせ、レンズ端に薄い曇り、衣服の暗部に細かなノイズを残すが、顔にはぼけ・ノイズ・曇り・強い影を重ねず、健康的で可愛く明瞭にする。参考画像1からは、成人顔の親しみやすい可愛さ、整った目鼻口、閉じ口の柔らかな笑顔だけを参照する。水着、体型、海辺、自撮り視点、自撮りポーズ、髪色、アクセサリー、美肌処理は参照しない。成人1名のみ、完全に服を着た非性的な日常。幼い顔、巨大なアニメ目、極端に小さな顎、人形肌、疲れ顔、口を開いた表情、広告風の仕上げ、スタジオ照明、身体強調、余分または融合した指、崩れた手、重複物、文字、看板、ロゴ、ラベル、透かしを避ける。

Use case: photorealistic-natural
Asset type: vertical 3:4 gallery photograph, an ordinary candid smartphone snapshot
Primary request: Create a new photorealistic image of one fictional 29-year-old adult Japanese woman on winter riverside steps, holding a plain unbranded can of hot cocoa naturally with both hands and giving the friend behind the camera a cute, gentle closed-mouth smile. Her attractive, clearly adult face is the first priority.
Input image: Image 1 is a face-aesthetic reference only. Borrow only the approachable cuteness, harmonious adult facial proportions, softly almond-shaped eyes, neat small nose, and gentle closed-mouth smile. Do not copy the swimsuit, body shape, beach, selfie viewpoint, pose, hair color, jewelry, skin retouching, or any other content.
Scene/backdrop: ordinary riverside steps in winter under a cloudy late-afternoon sky; muted river, bare vegetation, practical concrete or stone steps; believable everyday Japanese location.
Subject: one fictional adult woman, age 29, healthy and unmistakably adult. Fully dressed in a camel duffle coat, restrained red-and-gray check scarf, dark straight-leg jeans, and white sneakers. Both hands visibly and naturally wrap around a small plain unlabeled cocoa can near her torso. She looks toward the friend taking the picture.
Style/medium: authentic older-smartphone photo, approximately 35mm equivalent rear camera; realistic skin, subtle pores, natural hair strands, believable fabric and winter texture; candid rather than editorial.
Composition/framing: vertical 3:4, roughly knees or mid-shin to head, friend-shot at ordinary standing height, slightly imperfect casual framing. Keep the face healthy, cute, well exposed, sharply recognizable, and free of distortion.
Lighting/mood: overcast winter evening, soft cool ambient light with gentle warm color from skin and camel coat; a small portion of sky is naturally clipped to white.
Capture imperfections: only 2–3 mild camera-side flaws—thin lens-edge haze, fine noise in dark clothing areas, and limited sky highlight clipping. Do not place blur, noise, haze, distortion, or harsh shadow across the face.
Constraints: adult only; exactly one person; fully clothed; nonsexual everyday scene; natural anatomy and five fingers on each visible hand; realistic can grip; closed mouth; no selfie arm; no readable writing.
Avoid: childlike face, oversized anime eyes, tiny pointed chin, doll or wax skin, exhausted expression, open mouth, glamour retouching, cinematic advertising polish, studio lighting, shallow artificial portrait-mode blur, body emphasis, cleavage, exposed midriff, swimwear, suggestive pose, extra or fused fingers, malformed hands, duplicate objects, text, signage, logos, labels, watermark.
