Epic cinematic 8k wallpaper of Ellen Ripley, expression resolute yet scared, inspired by Alien movie. Dressed in a tank top, captured through a wide-angle lens in an action pose, half-body shot. Her forehead and cheeks glisten with sweat as she presses her back against the wall of the Nostromo spacecraft, standing in a shadowy room. The scene is brought to life with sci-fi elements, using ray tracing and rim lighting to highlight ultra-fine details. The composition is centered on her, depicting a stoic cinematic presence with dark, moody tones. Enhanced by Rembrandt lighting and high contrast, the focus remains shallow. RTX ray tracing and ambient lighting enhance realism, achieving an ultra-realistic, octane-rendered effect in 8K quality.
