请根据【主题：写人物名字】创作一张高完成度、高叙事张力、适合系列化发布的「暗潮群像封面 / Shadow Ensemble Cover」。
这不是普通角色插画，也不是简单的战斗海报，而是一张具有小说封面感、漫画主视觉感、游戏宣传感和暗黑奇幻插画感的“群像式动作封面”。画面需要通过一个巨大的精神核心人物、多个中景动作角色、背景威胁元素、局部能量光效和留白标题区，共同构成一个完整的角色阵营与世界观封面。
【基础设定】
主题：【主题，例如咒术战斗 / 暗黑西游 / 赛博猎人 / 山海经猎妖队 / 末日幸存者 / 魔法学院战斗团】
作品名：【作品名】
系列名 / 品牌名：【品牌名或系列名】
副标题：【副标题】
风格方向：【风格方向，例如暗黑奇幻、复古漫画封面、手绘厚涂、奇幻小说封面、游戏主视觉】
主色调：【主色调，例如墨绿黑灰 / 深蓝霓虹 / 暗棕金红 / 沙黄铁锈 / 深紫金色】
点缀色：【点缀色，例如血红能量、青绿色法术光、金色神光、蓝色雷电】
画幅比例：【画幅比例，例如2:3竖版 / 3:4竖版 / 4:5竖版 / 9:16竖版】
【画面结构】
采用竖版封面构图。画面中必须有一个体量巨大的主视觉人物，作为整张图的精神核心和气质压场元素。这个人物可以是侧脸、半身像、背影、正面凝视或巨大轮廓，占据画面右侧、上方或背景主区域，表情冷静、神秘、有压迫感，不一定参与战斗，但必须统领整张图的气质。
在中景安排3到6个动作角色，形成一个战斗阵营群像。角色之间需要有明确分工和姿态差异，例如冲锋、持刀、施法、防御、召唤、跳跃、警戒、远程攻击等。避免所有人物站桩，必须形成强烈的动作节奏和视觉动线。
背景中加入敌方威胁或世界观元素，例如怪物、巨兽、反派阴影、机械军团、妖魔、废墟、森林、异空间、战场烟雾或城市灾难。背景威胁不应喧宾夺主，而应像阴影一样包裹角色，增强危机感和叙事深度。
画面需要设置1到2个高饱和能量爆点，例如红色火焰拳、蓝色雷电、绿色诅咒气息、紫色魔法、金色神光或白色刀光。能量光效应集中在关键角色或关键武器上，形成视觉焦点，不要全画面平均发光。
【构图方式】
整体采用“大型精神核心人物 + 中景动作群像 + 背景威胁阴影 + 底部或侧边留白标题区”的结构。画面可以使用斜向动线组织角色，让角色群像从左上到右下、或从下方冲向中央，形成强烈推进感。
保留一块明显的留白标题区，建议位于左下、底部或画面侧边。留白区域使用米白、灰白、浅纸色或低饱和背景色，用于放置【品牌名 / 作品名 / 副标题】。标题排版应具有出版物封面感，可以使用优雅衬线字体、复古标题字、漫画封面标题或高级杂志式排版。文字区要清晰，不要被角色和背景完全遮挡。
插画边缘不要做成完整矩形铺满，可以使用不规则笔刷边缘、墨迹扩散、撕纸式留白或自然消散的方式，让角色和背景像从纸面中生长出来，增强手绘封面感和艺术质感。
【视觉风格】
整体风格应为手绘厚涂与漫画封面结合，具有纸张质感、笔触感、暗部层次和复古出版物气质。光影以低调暗光为主，背景压暗，人物轮廓清晰，局部能量光提供高对比焦点。画面不要过度干净，不要像普通AI光滑插画，应保留手绘纹理、纸张颗粒、边缘笔触和暗色雾气。
色彩上采用低饱和暗调为主，辅以少量高饱和能量色。整体氛围应具有压迫感、神秘感、战斗感和世界观厚度。
【画面目标】
最终画面应像一张成熟的奇幻小说封面、漫画特别篇封面、游戏角色阵营主视觉或IP宣传海报。它需要同时具备：
1. 清晰的主视觉人物；
2. 有动作节奏的角色群像；
3. 明确的敌方威胁或世界观背景；
4. 强烈但克制的能量光效；
5. 可阅读的标题文字区；
6. 复古手绘封面的整体质感。
请确保画面信息丰富但不混乱，角色层级清晰，视觉重心明确，阅读路径自然，适合后续替换主题继续生成同系列作品。
Please create a high-completion, high-narrative-tension, series-suitable "Shadow Ensemble Cover" based on [Theme: Write Character Name].
This is not an ordinary character illustration, nor a simple battle poster, but a "ensemble action cover" with a sense of novel cover, comic main visual, game promotional, and dark fantasy illustration. The image needs to combine a giant spiritual core character, multiple mid-ground action characters, background threat elements, local energy light effects, and a blank title area to form a complete character faction and worldview cover.
【Basic Settings】
Theme: [Theme, e.g., Jujutsu Battle / Dark Journey to the West / Cyber Hunter / Shanhai Jing Monster Hunting Squad / Doomsday Survivors / Magic Academy Combat Team]
Work Name: [Work Name]
Series Name / Brand Name: [Brand Name or Series Name]
Subtitle: [Subtitle]
Style Direction: [Style Direction, e.g., Dark Fantasy, Retro Comic Cover, Hand-painted Impasto, Fantasy Novel Cover, Game Main Visual]
Main Color Tone: [Main Color Tone, e.g., Ink Green Black Gray / Deep Blue Neon / Dark Brown Gold Red / Sand Yellow Rust / Deep Purple Gold]
Accent Color: [Accent Color, e.g., Blood Red Energy, Cyan-Green Magic Light, Golden Divine Light, Blue Lightning]
Aspect Ratio: [Aspect Ratio, e.g., 2:3 Vertical / 3:4 Vertical / 4:5 Vertical / 9:16 Vertical]
【Image Structure】
Adopt a vertical cover composition. There must be a massive main visual character in the image, serving as the spiritual core and atmospheric dominant element of the entire image. This character can be a side face, half-body portrait, back view, front gaze, or giant silhouette, occupying the right side, upper side, or main background area of the image, with a calm, mysterious, and oppressive expression, not necessarily participating in combat, but must dominate the atmosphere of the entire image.
Arrange 3 to 6 action characters in the mid-ground to form a combat faction ensemble. There needs to be a clear division of labor and posture differences among the characters, such as charging, holding a knife, casting spells, defending, summoning, jumping, standing guard, ranged attacking, etc. Avoid all characters standing still; a strong action rhythm and visual dynamic line must be formed.
Add enemy threats or worldview elements to the background, such as monsters, giant beasts, villain shadows, mechanical legions, demons, ruins, forests, alien spaces, battlefield smoke, or city disasters. The background threat should not overshadow the main subjects, but should wrap around the characters like shadows, enhancing the sense of crisis and narrative depth.
The image needs to set 1 to 2 high-saturation energy burst points, such as red flame fists, blue lightning, green curse aura, purple magic, golden divine light, or white blade light. Energy light effects should be concentrated on key characters or key weapons to form visual focal points, do not make the entire image glow evenly.
【Composition Method】
The overall structure adopts "Large Spiritual Core Character + Mid-ground Action Ensemble + Background Threat Shadow + Bottom or Side Blank Title Area". The image can use diagonal dynamic lines to organize characters, allowing the character ensemble to move from upper left to lower right, or rush from the bottom to the center, forming a strong sense of propulsion.
Retain an obvious blank title area, recommended to be located at the lower left, bottom, or side of the image. The blank area uses off-white, gray-white, light paper color, or low-saturation background color for placing [Brand Name / Work Name / Subtitle]. The title typography should have a sense of publication cover, using elegant serif fonts, retro title fonts, comic cover titles, or high-end magazine-style layouts. The text area must be clear and not completely obscured by characters and the background.
The edges of the illustration should not be a completely filled rectangle; irregular brush edges, ink diffusion, torn paper blank areas, or natural dissipation can be used, making the characters and background seem to grow out of the paper, enhancing the hand-drawn cover feel and artistic texture.
【Visual Style】
The overall style should be a combination of hand-painted impasto and comic covers, with paper texture, brushstroke feel, dark layer depth, and retro publication temperament. Light and shadow should be mainly low-key dark light, with the background darkened, character outlines clear, and local energy light providing high-contrast focal points. The image should not be overly clean, nor like ordinary smooth AI illustrations; it should retain hand-drawn textures, paper grains, edge brushstrokes, and dark fog.
Color-wise, adopt mainly low-saturation dark tones, supplemented by a small amount of high-saturation energy colors. The overall atmosphere should have a sense of oppression, mystery, combat, and worldview thickness.
【Image Goal】
The final image should look like a mature fantasy novel cover, comic special edition cover, game character faction main visual, or IP promotional poster. It needs to simultaneously possess:
1. A clear main visual character;
2. A character ensemble with action rhythm;
3. Clear enemy threats or worldview background;
4. Strong but restrained energy light effects;
5. A readable title text area;
6. The overall texture of a retro hand-drawn cover.
Please ensure the image information is rich but not chaotic, character hierarchy is clear, visual center of gravity is clear, reading path is natural, and it is suitable for subsequently replacing themes to continue generating works of the same series.
