Epic cinematic 8k wallpaper of Ellen Ripley, her face a blend of determination and fear, from the Alien movie, clad in a snug tank top, wide angle perspective, action-oriented posture, captured in a half-body shot; forehead and cheeks glistening with sweat, framed in a close-up, central composition as she presses her back against the cold, metallic wall of the Nostromo space shuttle. She stands amidst the shadows of a dimly lit sci-fi environment, enhanced with Ray Tracing, rim lighting accentuating her features, ultra-detailed with movie-quality fidelity, stoically rendered with a dark and moody ambiance, featuring lumen reflections and subtle ambient lighting. The scene is imbued with a 4k vogue aesthetic, utilizing Rembrandt lighting for high contrast. The shallow focus draws attention to her expression, utilizing RTX ray tracing lighting for a hyper-realistic effect with octane render in glorious 8K resolution.
