Poster balo mini nữ đi chơi

Create a complete vertical 9:16 promotional handbag thumbnail/poster, not a plain single image. Use [ảnh người mẫu] as the exact female model reference and [ảnh sản phẩm] as the exact mini backpack reference. Design a realistic Vietnamese fashion poster showing the female model wearing or carrying the exact mini backpack naturally. Include one large hero image, a front-view product close-up, strap-detail panel, storage-capacity icons, and 3 small preview frames showing side view, back carry, and casual outing styling. Add a bold Vietnamese headline and a short subheadline. Keep the backpack as a clear main product and make the overall layout clean, attractive, and commercial. No watermark.
