A stunning close-up portrait of a girl with an innocent, frowning expression and a slender athletic build, captured in a dynamic action pose. She is wearing an advanced combat exo-armor suit featuring a closed breathing system and a compact, sci-fi helmet with a high-tech glossy visor. The helmet is illuminated in a cinematic style. The setting is a detailed, photorealistic interior reminiscent of the TV show The Expanse, enhanced by vibrant neon and volumetric lighting. Shot with a Canon EOS 5D Mark IV DSLR at an aperture of f/8, a shutter speed of 1/250 sec, and ISO 100, the scene exhibits exceptional depth of field and hyper-realism. Natural reflections accentuate textures, and the lighting highlights a flowing hair tail, a bare neck, and subtle details like tinted glass. The character's physique is slender with narrow hips, depicted in an anime-inspired style with striking bright light effects and symmetrical design elements. Avoiding any imperfections such as deformed or extra limbs, the composition maintains perfect anatomical proportions for a flawless, captivating visual.
