Generate a horizontal 4:3 high-definition "Brand Packaging Design Proposal Board". 【Theme】: 【fill in product theme】 【Brand name】: 【fill in brand name】 【Series name】: 【fill in series name】 【Product contents】: 【fill in main product + 3 sub-products / SKUs】 【Style direction】: 【cute & childlike / young & energetic / light lifestyle / trendy-sweet / healthy & natural / pet-friendly / retro food feel / premium light-brand feel】 【Main color】: 【fill in main color】 【Accent color】: 【fill in accent color】 【IP / illustration elements】: 【fill in character, mascot, ingredient or graphic elements】 【Main headline copy】: 【fill in headline】 The composition uses a "large main-color background + irregular color blocks as a base + collage of multiple packaging mockups + proposal-board layout" structure. Must include: 1. One largest hero package as the primary visual center 2. 2–3 sub-packages / SKUs showing the series extension 3. A set of supporting packaging, combo packs, gift boxes or sample packs 4. Product-related ingredients, props or symbolic elements 5. An original IP / mascot, which may appear on the packaging or as a sticker in the image 6. A bold central Chinese headline 7. 01 / 02 / 03 numbered labels 8. A little English handwriting, such as PACKAGE DESIGN, BRAND SYSTEM, NEW FLAVOR 9. A few hand-drawn sketches, arrows, circle annotations, line art and cloud-shaped text bubbles The overall effect should look like a quick preview of a real packaging design proposal: with a sense of brand, series, portfolio and social-media shareability. The packaging needs real printing texture, paper box / plastic bag / cup / can materials, crisp edges, natural perspective and unified lighting and shadows. Avoid: no real brand trademarks, no garbled text, no deformed packaging, no low resolution, no cheap e-commerce promo style, do not pile all the packaging together, do not turn it into an ordinary product poster.
