Close-up medium shot of Petra Arkanian, one of the top students at Battle School, floating in the zero-gravity Battle Room. Petra is dressed in her Battle School uniform, her posture poised and ready for action. Her expression is fierce and focused, with her eyes locked on her target. Her hair is tied back, but a few strands float freely due to the zero-gravity environment. The background features the vast, star-filled space outside the Battle Room's transparent walls, with other cadets maneuvering in the distance. This shot highlights Petra's skill and determination in the face of rigorous training and combat simulations.                                           ,RAW photo, subject, 8k, uhd, (high quality), detail
