A full shot body photo capturing a devout sister of battle, showcasing a beautiful woman in a sci-fi nun armor, standing majestically in front of a vibrant stained glass window. Her face is symmetrical and intricately detailed, with reflective eyes framed by dark eyebrows and subtle mascara. The scene is set against marble walls, with dust particles illuminated by detailed lighting. Dramatic rim lighting and chiaroscuro effects enhance the atmosphere. The composition is inspired by professional impressionism, reminiscent of Waterhouse's and Constable's oil paintings, with influences from Studio Ghibli, creating a sense of high detail and intricacy.
