Epic cinematic 8k wallpaper of Ellen Ripley, her face a mixture of determination and fear, from the Alien movie, clad in a sleeveless white tank top. The scene is shot in wide angle with an action pose, capturing a half-body portrait. Her forehead and cheeks glisten with sweat, emphasizing intensity. Positioned against the wall of the Nostromo space shuttle, she stands in a shadowy, futuristic room. The image employs Ray Tracing and rim lighting to emphasize her features, providing ultra-detailed, high-quality cinematic aesthetics. The atmosphere is dark and moody, with lumen reflections and ambient lighting, reminiscent of a high-fashion photoshoot. The Rembrandt lighting style provides high contrast, and a shallow focus enhances the tension, all enhanced by RTX ray tracing lighting and ultra-realistic rendering in octane, presented in 8K resolution.
