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.

围绕具体饮料主题生成一张带有手作感的饮品视觉：真实透明杯装冷饮作为唯一主体，杯身放在有细微颗粒质感的地面或桌面上，主体位于视觉重心偏下的位置，杯口、冰块、液体分层和杯壁反光清晰可见，饮料本身承担最鲜明的情绪色。背景不是装饰布景，而是一整片被自然光切开的粗糙表面，大块柔和光斑与深浅阴影形成安静的空间层次，让主体像被阳光偶然照亮。画面上方放置短促、圆润、厚重的饮品名称字样，字形低对比、边缘柔软、间距稳，下面搭配一行轻细斜体小字，形成轻快但克制的阅读节奏。杯子周围加入极简手绘线描：一个小人物与杯口产生互动，旁边有细线小动物、弧形点线、蝴蝶结或飘带式白线装饰，线条像随手画在照片表面，既不遮挡饮品，也不抢走主体。色彩从饮料主题自身的材质、温度与情绪中提取，保留大面积低饱和结构底色、清晰明暗层次、少量高饱和透明饮料色、柔和浅色文字和黑白细线的角色关系；整体保持明亮清透、自然有生气，允许胶片颗粒和轻微暗角增加质感，但不能把画面处理成浑浊、陈旧或灰暗。最终效果应像一张被阳光、饮料色和手绘小故事共同完成的生活方式海报，真实摄影质地与童趣线描精确叠合，安静、清爽、可记忆。

想发竖版 3:4: 做一杯薄荷青柠冷泡茶，杯中有青柠片、透明冰块和很淡的茶色
画面上方的字: “薄荷青柠冷泡”，副字“下课后来一杯，把热气放掉”
小插画怎么放: 线描小人趴在杯口吹一片薄荷叶，小鸟停在吸管上，线条要像随手补上的白色涂鸦
受众: 学校附近饮品店下午档宣传，清爽但不幼稚
