1. Soft Cozy Pastel Sticker Portrait

Transform the uploaded photo into a soft, cozy minimalist digital illustration while preserving the original composition, perspective, pose, environment, and all recognizable objects from the image.
Style: Recreate the entire scene in a clean pastel illustrated style with smooth rounded edges, muted colors, and minimal facial details. The person should maintain their original pose and overall appearance but be reimagined as a cute stylized character with rosy blush cheeks, soft gentle expressions, simplified anatomy, and clean flat clothing shapes.
Effect: Add a bold clean white outline around the main subject only to create a sticker-like cutout effect — making the character appear as if they are a physical illustrated sticker placed directly on top of the illustrated background scene behind them.
Environment: Illustrate the background in the same pastel flat style but slightly simpler and less detailed than the character — café furniture, plants, windows, walls, and people in the background should all be visible but softly simplified into flat illustrated shapes with muted tones.
Mood & Lighting: Use soft warm indoor lighting, gentle shadows, and a calming pastel color palette throughout. The overall color temperature should feel warm, clean, and airy — like a bright cozy café on a quiet morning.
Final feel: The result should feel warm, adorable, polished, and lifestyle-oriented — exactly like a Korean or Japanese pastel sticker character placed inside a beautifully illustrated café scene, matching the composition of the original photo precisely.

Effect: Add a bold clean white outline around the main subject only to create a sticker-like cutout effect — making the character appear as if they are a physical illustrated sticker placed directly on top of the warm golden illustrated background scene behind them.
Environment: Illustrate the background in the same warm pastel flat style but slightly simpler than the character — golden window light streaming in, long soft shadows across furniture, warm wooden surfaces, potted plants glowing in sunlight, and soft blurred people in the background all rendered in flat illustrated warm tones.
Mood & Lighting: Use strong warm side lighting coming from a large window, casting long golden shadows across the scene. The overall color palette should sit in warm peach, honey amber, cream, and soft terracotta — like the most beautiful late afternoon light pouring through a café window.
Final feel: The result should feel warm, glowing, dreamy, and golden — exactly like a lifestyle sticker portrait captured in the most beautiful light of the day, matching the composition of the original photo precisely.

Style: Recreate the entire scene in a cool-muted pastel illustrated style with smooth rounded edges, misty soft tones, and minimal facial details. The person should maintain their original pose and overall appearance but be reimagined as a cute stylized character with soft pink blush, a calm contemplative expression, simplified anatomy, and cozy layered clothing shapes rendered in muted cool tones.
Effect: Add a bold clean white outline around the main subject only to create a sticker-like cutout effect — making the character appear as if they are a physical illustrated sticker placed directly on top of the illustrated rainy background scene behind them.
Environment: Illustrate the background in the same cool pastel flat style but slightly simpler than the character — rain streaks visible on large windows, soft condensation blur on the glass, warm lamp glow contrasting against the cool grey outside light, indoor plants, and cozy furniture all rendered in flat muted illustrated shapes.
Mood & Lighting: Use cool grey outdoor light filtered through rain-streaked windows contrasted with warm soft indoor lamp glow. The overall palette should sit in periwinkle blue, misty grey, soft cream, muted sage, and warm amber lamplight — like the coziest rainy afternoon spent indoors.

The person should maintain their original pose and overall appearance but be reimagined as a cute stylized character with soft rosy cheeks, a gentle absorbed expression, simplified anatomy, and clean flat clothing rendered in warm neutral tones.
Effect: Add a bold clean white outline around the main subject only to create a sticker-like cutout effect — making the character appear as if they are a physical illustrated sticker placed directly on top of the beautifully illustrated bookshop background scene behind them.
Environment: Illustrate the background in the same dusty pastel flat style but slightly simpler than the character — floor to ceiling bookshelves filled with flat illustrated books in varying pastel spines, soft reading lamps casting warm pools of light, wooden ladders, small potted plants on shelves, and warm wooden floors all rendered in simplified flat illustrated shapes.

Mẹo để tạo ảnh đẹp hơn

• Sử dụng ảnh có độ phân giải cao và đủ sáng. Ảnh được chụp dưới ánh sáng tự nhiên hoặc gần cửa sổ thường cho kết quả tốt hơn.
• Đảm bảo khuôn mặt hiển thị rõ ràng. Góc chụp chính diện hoặc nghiêng nhẹ sẽ giúp AI nhận diện và tái tạo khuôn mặt chính xác hơn.
• Chọn bối cảnh phù hợp với prompt. Ví dụ, nếu dùng prompt Rainy Day Indoor, hãy chọn ảnh chụp trong nhà gần cửa sổ vào ngày mưa hoặc có ánh sáng dịu. Với Golden Hour Window Seat, ảnh chụp vào buổi chiều gần cửa sổ sẽ mang lại kết quả tự nhiên và hài hòa hơn.

Lưu ý: Bạn có thể giữ nguyên các prompt bằng tiếng Anh khi sử dụng với Gemini AI để đạt kết quả chính xác nhất. Không nên dịch prompt sang tiếng Việt vì có thể làm thay đổi cách AI hiểu yêu cầu.
