A stunning close-up three-quarter portrait of a girl with a frowning yet innocent expression. She has a slender athletic build, depicted in a dynamic action pose that emphasizes her expressive features. The girl is clad in a sleek combat exo armor suit, complete with a closed system breathing apparatus and a sci-fi cosmic exo helmet. The helmet features a high-tech glossy visor with cinematic face lighting. The interior is intricately detailed in a style reminiscent of TV's "The Expanse," bathed in neon and volumetric lighting, with illumination emanating from various points in the room. The scene is captured with a Canon EOS 5D Mark IV DSLR, set to an aperture of f/8, shutter speed of 1/250 sec, and ISO 100. The image showcases depth of field, hyper photorealism, and natural reflection textures. Her hair is styled into a cinematic hair tail, with a few strands sticking out behind a bare neck. She stands with narrow hips, wearing heels, surrounded by bright, almost blinding light that glints off gold-tone rivets in her armor. The scene avoids imperfections, maintaining symmetry and avoiding elements like deformed anatomy, extra limbs, and other unwanted mutations. The image is free of any artifacts, ensuring a clean, detailed, and lifelike portrayal.
