Poster demo video review sneaker nữ

Create a complete vertical 9:16 promotional thumbnail/poster, not a plain single image. Use [ảnh người mẫu] as the exact model reference and [ảnh sản phẩm] as the exact sneaker reference. Design a Vietnamese ad thumbnail for an AI tool that automatically creates sneaker review videos. Include a bold headline at the top, a short subtitle, a large hero image of the model holding or wearing the sneaker, two small input panels showing model image and sneaker image, a phone-mockup output panel, arrows or glow effects to explain the workflow, and several small preview frames at the bottom showing other review angles. Preserve the model identity and the sneaker design accurately. The poster should feel youthful, sporty, clean, and sales-focused, optimized for TikTok, Reels, and affiliate content. Use readable Vietnamese text, good spacing, strong visual hierarchy, and no messy clutter. No watermark, no anatomy errors, no unreadable text.
