Create an ultra-realistic, close-up portrait of a cyberpunk skeleton assassin wearing a black biker leather jacket with a high collar, captured in breathtaking detail. His long, disheveled hair flows dramatically in the wind (long-hair:1.4). The skeletal face is illuminated with a soft, ominous glow, grinning menacingly at the camera with an evil, confident expression. The scene is infused with atmospheric haze, enhancing the cinematic composition, with soft, moody shadows that carve depth into every element of the image. The lighting is dynamic and captivating, blending vibrant neon highlights with subtle contrast, creating an otherworldly yet grounded feel. The assassin stands against a richly detailed cyberpunk background, with blurred, colorful lights and urban textures. Captured with the precision of a Leica Q2 Summilux 35mm f/1.2 ASPH lens, the shot is in 8K Ultra HD, with hyper-detailed textures and impeccable focus on every element—from the intricate bone structure to the leather jacket's glossy texture. This masterpiece radiates intensity and raw power, perfect for a high-quality wallpaper. Every element is rendered in stunning UHD, with vibrant tones, complex layers of detail, and a film-like, epic composition that immerses the viewer completely. Hyperrealistic and cinematic, this image sets a new standard for visual storytelling.
