A stunning close-up portrait highlighting a frowning, innocent expression on a slender, athletic girl in a dynamic pose. She's clad in an advanced combat exo-armor suit featuring a closed breathing system, along with a compact sci-fi cosmic helmet boasting a high-tech glossy transparent visor and cinematic face lighting. This scene is set in a highly detailed interior reminiscent of TV's The Expanse, complete with neon and volumetric lighting illuminating the room, creating a dramatic effect. Shot with a Canon EOS 5D Mark IV DSLR using an aperture of f/8, a shutter speed of 1/250 sec, and ISO 100, the image showcases a depth of field with super detailed, hyper photorealistic textures. The natural reflection on surfaces, cinematic lighting on her hair tail, a bare neck, and stray hairs complement the futuristic setting. Additional elements like tinted glass and a sense of symmetry round out the composition, while avoiding any exaggerated or distorted anatomy, ensuring a polished, visually compelling scene.
