Full portrait close-up three-quarter in focus, featuring a stunning face with a frowning yet innocent expression. A slender athletic girl strikes a dynamic action pose, emphasizing expressive features of her chest and thighs. She wears an advanced combat exo armor suit with a closed breathing system and a compact sci-fi cosmic helmet. The suit is detailed with a high-tech glossy transparent visor with cinematic lighting on the helmet's face. The scene is set within an intricately designed interior inspired by the style of TV's The Expanse, featuring neon and volumetric lighting illuminating the room. Photographed using a Canon EOS 5D Mark IV DSLR with settings of aperture f/8, shutter speed 1/250 sec, ISO 100 to create a hyper-realistic depth of field. Attention to detail includes natural reflection textures and cinematic lighting highlighting her hair tail and bare neck. Transparent elements like tinted glass and asymmetrical designs create an engaging visual, while avoiding any distorted anatomy or unnatural additions. The overall aesthetic combines elements like sleek goth styles alongside advanced technology, ensuring a coherent and visually striking composition.
