Thumbnail balo bỉm sữa đa ngăn

Create a complete vertical 9:16 promotional mother-and-baby thumbnail/poster, not a plain single image. Use [ảnh người mẫu] as the exact female model reference and [ảnh sản phẩm] as the exact diaper backpack reference. Design a realistic Vietnamese ad thumbnail showing the female model carrying or presenting the exact diaper bag. Include one large hero image, an open-bag compartment panel, storage-capacity icons, bottle-pocket detail, and 3 small supporting frames showing front view, side view, and travel-ready use. Add a bold Vietnamese headline and a short subheadline. Clean, practical, modern, and clearly commercial. No watermark.
