Moonlit rooftop and floating mountain-city assassin

An ultra-detailed 4K cinematic fantasy artwork: a mysterious hooded assassin crouches on the edge of an ancient temple roof inspired by traditional Japanese aesthetics, overlooking a magnificent mountain city floating above the clouds. He wears an elegant black tactical ronin outfit decorated with intricate silver embroidery, layered armor, a flowing cloak, and subtle deep-red accents.

He holds an extraordinary katana in one hand, half drawn from its sheath, radiating a subtle electric-blue energy glow. Intricate runes are engraved on the steel blade, whose sharp edge reflects the moonlight. Most of his face is hidden beneath the hood, with only his sharp eyes faintly visible. His cloak and hair whip dramatically in the wind.

In the background, a huge bright full moon hangs in a deep midnight-blue sky filled with stars and dramatic swirling clouds. Floating mountains, waterfalls passing through the clouds, ancient pagodas, and glowing lanterns scattered throughout the valleys create a majestic vista. Cherry-blossom petals drift through the air, some close to the lens, creating beautiful cinematic depth of field.

超精细 4K 电影级奇幻艺术作品：一名神秘的兜帽刺客蹲伏在一座受日本古风启发的古老寺庙屋顶边缘，俯瞰着一座漂浮于云层之上的壮丽山城。他身着优雅的黑色战术浪人装束，饰有复杂的银色刺绣、层叠铠甲、飘逸斗篷以及微妙的深红色点缀。

他单手握持一把非凡的武士刀，刀刃半出鞘，散发着微妙的电蓝色能量光芒，钢刃上刻有错综复杂的符文，锋利的边缘反射着月光。他的面容大部分隐藏在兜帽之下，仅隐约可见锐利的双眼。斗篷和头发在风中剧烈飘动。

背景中：一轮巨大的明亮满月悬挂在深邃的午夜蓝天空中，繁星点点，戏剧性的云层缭绕；漂浮的山脉、穿过云层的瀑布、古老的宝塔以及散布在山谷中的发光灯笼交相辉映。樱花花瓣在空中飘落，部分靠近镜头，营造出美丽的电影级景深效果。
