Retro Beverage Advertisement Poster

Around the specific beverage theme, generate a bright, upbeat, vintage-style commercial advertising visual: at first glance, the image should establish a memorable identity through an oversized, thick, rounded-corner main logotype — its letterforms like soft, puffed-up signage blocks, filled with a light color, clean-edged, and dominating the visual weight at the top. The beverage's main form should appear at the bottom center with a real product-photography texture, enlarged in close-up, with clear highlights, condensation or liquid sheen, and natural shadows, extending forward to cover the background and part of the text, creating a strong front-to-back layering between the flat graphics and the real product. The background uses radiating blocks spreading outward from near the subject, with sharp edges and a dense rhythm, creating a sense of speed and cheerful impact. The text system has three layers: the main logotype is largest, the subtitle uses a narrow, tall, retro capital typeface tucked right below it, small-sized information is scattered in the corners, and short handwritten italic phrases cut across the area around the subject in arcs or diagonals, with a few white line-art arcs, sparkle symbols, and small marks added to enhance the rhythm. Colors should be drawn from the beverage's flavor, materials, and brand mood, preserving a large area of clear, bright structural color, a small amount of strong-contrast accent color, light-colored information text, and the role relationship with the warm subject color; overall it should be high-brightness, high-saturation yet clean and airy, with clear tonal steps and a fresh, playful, energetic mood, avoiding dull, dirty-looking grime, muddy overlays, and low-energy vintage grain. —————— Display ratio: {argument name="ratio" default="portrait 3:4"}, suitable for a mall beverage pop-up-stand standee Main subject of the image: {argument name="subject" default="a cup of lychee iced tea close to the bottom, with lychee flesh and ice cubes inside the cup, the straw poking out at a slight angle"} On-site text: {argument name="text content" default="main logotype 「荔枝开场」, subtitle reads "LYCHEE ICED TEA", small corner text reads "周末限定 100 杯"} How it should feel to passersby: like a sweet drink sign that catches your eye from a distance while walking through a shopping area
