勇闯幽暗魔界的原创奇幻冒险海报

创作一张原创电影感奇幻冒险海报：一位年轻成年冒险者站在幽暗魔界的巨大裂谷边缘，身穿朴素但耐用的旅行服和短斗篷，手持发出微弱暖光的探险灯，面对远处从黑色岩层、熔岩雾气和古老石门之间升起的巨大恶魔生物剪影。前景是潮湿岩石、碎裂石阶和少量发光符文状纹理，但不要可读文字；中景突出孤独的英雄轮廓与狭窄的光束，背景展现深不见底的地下城市、悬浮岩岛和红黑色风暴云。构图采用低角度广角史诗视野，主体位于下方中央，裂谷和石门形成引导线，使用冷蓝黑环境与克制的熔岩橙红对比，体积雾、飞灰和微小火星增加深度。整体气质紧张、勇敢、神秘，像高端原创奇幻电影概念海报；人物和恶魔均为原创设计，避免任何现有动画、漫画、电影或游戏角色的相似外观。不要品牌、商标、可读标题、版权标志、血腥、武器细节、畸形或水印。

【English Prompt】
Create original cinematic fantasy-adventure key art: a young adult explorer stands at the edge of a vast dark underworld chasm, wearing practical travel clothes and a short cloak, holding a small exploration lamp that casts a restrained warm glow. In the distance, enormous original demonic silhouettes rise between black rock strata, lava mist and an ancient stone gate. The foreground contains wet rock, broken steps and a few luminous rune-like textures, but no readable writing. The middle ground emphasizes the solitary hero silhouette and narrow light beam; the background reveals a bottomless subterranean city, floating rock islands and red-black storm clouds. Use a low-angle wide epic view with the subject low and centered, the chasm and gate forming leading lines, and a cold blue-black environment contrasted with restrained lava orange-red. Add volumetric fog, drifting ash and tiny embers for depth. The mood is tense, brave and mysterious, like premium original fantasy-film concept art. All characters and creatures must be original designs with no resemblance to existing animation, manga, film or game characters. Avoid brands, trademarks, readable title text, copyright symbols, gore, weapon detail, deformation and watermarks.
