The composition adopts a structure of "large main color background + irregular color block base + multi-packaging mockup collage + proposal board layout."

Requirements include:
1. A large main package serving as the primary visual center
2. 2–3 sub-packages/SKUs, showcasing series extensions
3. One set of auxiliary packaging, combo packs, gift boxes, or tasting packs
4. Ingredients, props, or symbolic elements related to the product
5. Original IP / mascot, which can appear on packaging or screen stickers
6. Prominent Chinese headline
7. 01/02/03 Numbered labels
8. A small amount of English handwriting, such as PACKAGE DESIGN, BRAND SYSTEM, NEW FLAVOR
9. A small amount of hand-drawn sketches, arrows, circles, line art, and cloud text boxes

The overall effect should look like a quick preview of a real packaging design proposal:
It should have a sense of brand, series, portfolio, and social media communication.

Packaging should have a realistic print texture, with materials such as paper boxes, plastic bags, cups, or cans, clear edges, natural perspective, and unified light and shadow.

Avoid:
Don't use real brand trademarks, don't use garbled text, don't distort packaging, don't use low resolution, don't use cheap e-commerce promotional styles, don't pile all packaging together, don't make ordinary product posters.
