手绘包装提案板产品介绍海报

为{product_name}创作一张竖版手绘包装提案板，融合真实精致的产品成品渲染、包装设计草图与清晰的品牌概念开发过程。画面中央放置最完整、最吸睛的{product_name}包装成品，呈现真实材质、立体光影、商业级质感与协调且有品牌感的配色。产品周围加入多组随性辅助研究：不同角度包装草图、结构草图、局部造型探索、手持展示小稿、包装展开思路和字体排版试验。加入自然的深色手绘线稿、箭头、圈画、符号和少量简短可读的手写批注，保持版式松弛但有秩序、节奏和视觉层级，并适度加入与产品相关的图形元素。如果提供产品参考图，保留其核心外观、包装形态、材质、颜色和品牌识别；如果没有参考图，则为{product_name}设计统一合理的包装。最终效果应像高级品牌设计创意评审提案板，不要做成普通电商详情页或促销海报。不要随机标志、水印、密集段落或低幼卡通风格。

【English Prompt】
Create a vertical hand-drawn packaging proposal board for {product_name}, combining a realistic finished product rendering with packaging design sketches and a clear brand concept development process. Place the most complete, eye-catching {product_name} package in the center with realistic material, dimensional light, refined commercial texture, and a coordinated brand-aware color system. Surround it with multiple loose auxiliary studies: alternate package angles, structural sketches, partial form explorations, a hand-held display draft, an unfolded packaging idea, and typography layout experiments. Add natural dark hand-drawn lines, arrows, circles, symbols, and minimal handwritten annotations, keeping all annotation text short and legible. Use a relaxed but ordered layout with rhythm, visual hierarchy, and tasteful product-related motifs. If a product reference image is provided, preserve its core appearance, packaging form, material, color, and brand identity; otherwise invent a coherent package for {product_name}. The result should feel like a high-end creative review board, not an e-commerce detail page or promotional poster. No random logos, watermark, dense paragraphs, or childish cartoon styling.
