AI Prompt for Minimalist Product Poster Design with Vintage Figure and Herbal Anti-Itch Cream

"A minimalist clean poster on a warm light beige studio background with a subtle wall-to-table horizon line, lots of negative space, and soft diffused lighting. Center-right stands a full-body vintage silent-film comedian resembling {argument name="character type" default="Charlie Chaplin"}, wearing a black bowler hat, dark worn suit, vest, white shirt, tie, oversized trousers, and old leather shoes, holding a thin curved cane in one hand and smiling gently. His other arm is extended in a presentation gesture toward a large green jar of {argument name="product name" default="anti-itch cream"} placed in the foreground at center. The jar has a white screw cap, translucent green body, and a bright yellow-green label with Chinese medicine-style packaging details, including small Chinese characters and the English text {argument name="label text" default="ANTI-ITCH CREAM"}. A realistic human hand rises from below to support the jar from underneath, making the product the visual focal point. Add fresh green mint leaves around the base of the jar and near the character’s feet for a natural herbal cue. Composition should feel like a modern advertising poster: product large and centered, character slightly behind and to the right, clean cutout look, soft shadows, crisp edges, muted neutral palette with the green jar as the main color accent. No headline, no extra layout elements, no clutter, no border. Include a tiny four-point sparkle icon in the lower right corner. Aspect ratio vertical poster, polished commercial photomontage style."
