手绘感薄荷青柠冷泡茶饮品视觉海报

Generate a beverage visual with a handmade feel centered on a specific drink theme: a real transparent cup of cold drink as the sole subject, placed on a ground or tabletop with subtle grainy texture. The subject is located below the visual center of gravity. The cup rim, ice cubes, liquid layering, and reflections on the cup wall are clearly visible, with the drink itself carrying the most vivid emotional color. The background is not a decorative set but a whole rough surface cut by natural light; large soft light spots and deep/shallow shadows form a quiet spatial hierarchy, making the subject look as if accidentally illuminated by sunlight. Place short, rounded, and heavy drink name characters at the top of the screen, with low-contrast fonts, soft edges, and stable spacing, paired with a line of light, thin italic small characters below, forming a brisk but restrained reading rhythm. Add minimalist hand-drawn line sketches around the cup: a small figure interacting with the cup rim, accompanied by fine-line small animals, curved dotted lines, bows, or ribbon-style white line decorations. The lines look like they were casually drawn on the photo surface, neither blocking the drink nor taking away from the subject. Colors are extracted from the material, temperature, and emotion of the beverage theme itself, retaining a large area of low-saturation structural base color, clear light and dark levels, a small amount of high-saturation transparent beverage color, and the role relationship between soft light-colored text and black-and-white fine lines. The overall look remains bright, clear, natural, and lively, allowing for film grain and slight vignetting to add texture, but the image must not be processed to be muddy, old, or gloomy. The final effect should be like a lifestyle poster completed by sunlight, beverage colors, and hand-drawn small stories, with real photographic texture and childlike line drawings precisely overlapped, quiet, refreshing, and memorable.

Want to post in vertical 3:4: Make a cup of Mint Lime Cold Brew Tea, containing lime slices, transparent ice cubes, and a very light tea color.
Words at the top of the screen: "Mint Lime Cold Brew", subtitle "Have a cup after class, let the heat go away".
How to place small illustrations: A line-drawn small person lying on the cup rim blowing a mint leaf, a small bird perched on the straw, lines should be like white graffiti added casually.
Audience: Afternoon promotion for a drink shop near the school, refreshing but not childish.
