A stunningly beautiful young girl with a slender athletic figure and an innocent expression is portrayed in a three-quarter close-up portrait, her hair cascading down as she frowns slightly. She is dressed in a sleek combat sci-fi jumpsuit reminiscent of the style from the sci-fi series Battlestar Galactica. The scene is set in a photorealistic style, capturing the essence of a 90s sci-fi series set in deep space, with an oppressive and contrasting background that adds a sense of depth and intensity. The lighting is dramatic, with backlighting creating expressive shadows, conveying a gloomy and crushing atmospheric tension. The portrait is captured in a cinematic style from a low angle using a Canon EOS 5D Mark IV DSLR with an aperture of f/8, shutter speed of 1/250 sec, and ISO 100. The image is richly detailed and hyper-photorealistic, with textures that reflect natural light, enhanced by cinematic lighting filtering through tinted glass. Elements like symmetry, gold accents, and rivets add to the sci-fi aesthetic, while avoiding any distortions like deformations or multiple limbs, ensuring the portrayal remains elegant and lifelike.
