Prompt
Universal prompt:
Please generate a "hand-drawn packaging proposal board style" product presentation poster for 【产品名称】.
If I provide a product image, use that image as the main reference, preserving the product's core appearance features, packaging form, colors, materials, brand identity and overall temperament, and prioritize using the reference image's dominant hue and color relationships in the design.
If I do not provide a product image, automatically generate a product appearance and packaging design appropriate to 【产品名称】's positioning, and automatically choose natural and reasonable primary, secondary, and background colors according to the product attributes, category characteristics, and temperament.
Overall poster style requirements:
This is not an ordinary e-commerce detail page, nor a simple studio photograph poster, but a creative proposal board that integrates "finished product photo + packaging design sketches + brand concept development process." The whole should present as a high-aesthetic, high-completion brand design display, like a designer presenting a packaging concept proposal.
Image requirements:
- Vertical composition
- Use a unified, brand-feeling primary background color, with the background color determined naturally by the product itself, not fixed to any single color
- Color scheme should coordinate with product attributes: if there is a reference image, prioritize inheriting the reference's main and brand colors; if no reference image, generate a reasonable color scheme automatically based on the product name
- Place the most complete and eye-catching product main visual in the center, with realistic texture, three-dimensional lighting and commercial finished-product rendering
- Add multiple auxiliary visual elements around the product: packaging sketches from different angles, structural sketches, close-up form explorations, small hand-held display thumbnails, packaging dieline/unfolded ideas, brand wordmark/typography experiments
- Include natural, casual black or dark hand-drawn linework, arrows, circles, symbols, and handwritten Chinese annotations to give a strong "design process" and "creative proposal" feeling
- Finished product imagery should be relatively refined and realistic, while sketch parts should be relatively loose and lively, creating a contrast of "finished product + design sketches"
- Layout should feel relaxed and free, but overall ordered, rhythmic, and have a visual center, reflecting high-end graphic design sensibility
- May appropriately add small graphics, icons or playful elements related to the product to enhance brand memorability
