A stunning girl in a dynamic action pose, wearing a sleek combat exo-armor suit with a closed-system breathing apparatus. Her expression is a mix of frowning and innocence, with a focus on her slender athletic figure. The exo-suit is complemented by a compact sci-fi cosmic helmet featuring a high-tech glossy transparent visor with cinematic lighting illuminating her face. The scene is set in a highly detailed and intricately designed interior reminiscent of TV shows like The Expanse, accented with neon lighting and volumetric room illumination. The ambiance is enhanced by natural reflection textures and cinematic lighting highlighting her hair, which is elegantly styled with a bare neck and strands sticking out. Using a Canon EOS 5D Mark IV DSLR, the shot boasts hyper-photorealism with a depth of field that captures intricate details like tinted glass and gold accents, with a symmetrical and visually balanced composition.
