A high-completion commercial campaign poster for a plush character brand, featuring a large, soft, huggable plush character as the main visual center, with realistic fluffy fur texture, round volume, stitching details, and a cute, healing expression. The character is set in a themed fantasy world that matches the event theme, such as a dreamy garden, amusement park, or party scene, with high-quality supporting elements like balloons, gift boxes, clouds, stars, ribbons, and themed props. The overall style blends plush texture, fairy tale charm, brand identity, and advertising feel, with soft, bright, and dreamy lighting and color palette. The composition is vertical for mobile screen (9:19.5 ratio), with the plush character as the first visual focus, surrounded by scene elements, and naturally reserved space for typography. The typography includes the brand name, event title (generated based on the event theme), subtitle, 3-5 key selling points, and auxiliary tags like NEW or LIMITED, arranged with modern sans-serif or rounded display fonts, combined with geometric shapes, sticker frames, lines, and decorative elements for a layered, design-forward poster look. The final image should look like a brand event key visual, suitable for social media, brand promotion, new product launch, or seasonal campaign.
