治愈系高级绘本感文字插画海报

With [Theme] as the core, design a 9:16 vertical healing-style text illustration poster.

Uniformly reconstruct [Work Characters] into a set of cute character systems with a sense of original design. The overall style is not ordinary 2D anime, but high-end children's picture book feel × mascot illustration × textured gouache poster × playful graphic character design.

Place the largest [Theme Main Title] in the center of the image as the strongest visual center; distribute multiple irregular hand-drawn color blocks around it, with auxiliary short sentence copy revolving around [Theme] placed in each color block.

Characters interact clearly with the text: hugging the main title, lying on the words, peeking from behind the words, holding up a corner of a word, resting next to the text, and performing actions around the small copy.

Character shapes are rounded, simple, graphic, doll-like, and anthropomorphic, with clear outlines, vivid expressions, and short, cute limbs, like designed cultural and creative mascots rather than ordinary Japanese manga characters.

The overall style adopts a hand-drawn poster style, with gouache, water-powder, pastels, colored pencils, paper grain, irregular brushstrokes, and a slight rough texture.

The color scheme uses a random but coordinated high-brightness soft color system, which can use cream colors, macaron colors, candy colors, spring garden colors, summer gummy colors, etc., with the central color block being more eye-catching and the background remaining light and clean.

【主题】 为核心，设计一张 9:16 竖版治愈系文字插画海报。

将 【作品角色】 统一重构为一组 具有原创设计感的可爱角色系统，整体不是普通二次元，而是 高级童趣绘本感 × mascot illustration × textured gouache poster × playful graphic character design。

画面中央放置最大号 【主题主标题】，作为最强视觉中心；周围分布多个不规则手绘色块，每个色块中放置围绕【主题】展开的辅助短句文案。

角色与文字产生明显互动：抱住主标题、趴在字上、从字后探头、托住字的一角、靠在文字旁边休息、围绕小文案做动作。

角色外形圆润、简洁、图形化、玩偶化、拟人化，轮廓清晰、表情生动、肢体短小可爱，像设计过的文创吉祥物，而不是普通日漫角色。

整体采用 手绘海报风格，带有 gouache、水粉、粉蜡笔、彩铅、纸张颗粒、不规则笔触和轻微粗糙纹理。

配色采用 随机但协调的高明度柔和彩色系统，可使用奶油色、马卡龙色、糖果色、春日花园色、夏日软糖色等，中央色块更醒目，背景保持浅色干净。
