夏日城市漫步照片拼贴，保留身份特征

Use case: identity-preserve style-transfer Asset type: vertical multi-panel summer citywalk collage for social post Primary request: create a bright summer citywalk photo-collage using the uploaded portrait photo as the appearance reference for the person. Scene/backdrop: a sunny tree-lined city street or park road in summer, warm green foliage, clean asphalt, bright daylight, soft shadows, casual outdoor citywalk atmosphere. Subject: the same young East Asian woman from the uploaded portrait photo, preserving her recognizable soft oval face, large brown eyes, natural nose and lips, skin tone, center hair part, gentle youthful expression, and overall facial identity. Keep her dark brown or black hair with two low braids or braid-based side sections, with a few loose summer flyaway strands. Do not change her into a blonde character. Outfit: summer casual streetwear, light and breathable. Use variations across panels such as a white short-sleeve tee, pale blue cropped shirt, light camisole with thin cardigan, pleated mini skirt or loose shorts, white socks, light sneakers, small cute crossbody pouch, and subtle hair ties. Clothing should feel fresh, sunny, youthful, and summery, not autumn or winter. No hoodie, no heavy sweater, no leg warmers, no boots, no thick knitwear. Composition/framing: one vertical collage made of 12 photo panels in a clean 3-column by 4-row grid. Each panel shows the same person in a different playful citywalk pose: standing with one arm raised, holding a phone selfie, squatting with hands on cheeks, walking, small jump, sitting on the ground, hand near hair, side pose, full-body pose, and close three-quarter portrait. Keep a casual snapshot rhythm with slight variation in crop and scale. Graphic overlays/text: add cute hand-drawn white doodles such as hearts, sun icons, wavy lines, sparkles, and simple summer stickers. All visible words must be in English only. Include short handwritten English phrases like "HAPPY SUMMER", "summer citywalk", "sunny day", and "citywalk" in a playful white marker style. No Chinese characters anywhere. Style/medium: photorealistic social-media collage, cute editorial street-snap style, glossy but natural, lively summer mood, natural skin texture, no plastic beauty filter. Lighting/mood: clear bright summer sunlight, green leafy shade, warm highlights, cheerful open-air energy. Color palette: fresh summer green, sky blue, soft white, pale yellow sunlight, light denim blue, clean cream tones, small pastel sticker accents. Textures/retouching: realistic fabric texture, natural skin detail, crisp hair and braid texture, road texture, handwritten marker doodles, clean grid edges.
