Packaging Design Proposal Board Prompt

Prompt

Please generate a “hand-drawn packaging proposal board” style product introduction poster for【{argument name="产品名称" default="奶粉"}】.  If I provide a product image, please use that image as the main reference, preserve the product’s core visual features, packaging form, colors, material, brand identity, and overall feel, and prioritize the main color palette and color relationships from the product image in the design.
