为主题角色制作一张宣传海报

为《我独自升级》主题角色制作一张宣传海报，采用垂直 Facebook 肖像帖子构图（4:5 比例，1080x1350）。使用层级结构，上方放置大元素，下方放置较小元素：顶部区域应以非常大的头部、阴影脸部轮廓、发光的眼睛，或成神宇（Sung Jin-Woo）的半身作为主要视觉主体，形成一个强大、即时可识别的标志性轮廓。

Create a promotional poster of a SOLO LEVELING-themed character with a vertical Facebook portrait post composition (4:5 ratio, 1080x1350). Use a hierarchy structure with large elements on top and smaller ones below: the top section should feature a very large head, shadowed face silhouette, glowing eyes, or half-body of Sung Jin-Woo as the main visual subject, forming a strong, instantly recognizable iconic silhouette.
