A full shot of a strikingly beautiful woman, depicted as a sister of battle, standing confidently with a bolt rifle in front of an intricate stained glass window. Her tanned skin features a subtle fleur de lys face tattoo, and her armor is adorned with wax seals. The composition highlights her symmetrical face, reflective eyes, dark, defined eyebrows, and expertly applied mascara and makeup. She wears a stunning piece of sci-fi nun armor, reminiscent of Warhammer 40k style, set against towering marble walls. The scene shimmers with dust particles, dramatic chiaroscuro lighting, and rim lighting that heighten the visual tension. This piece is a professional, majestic impressionism oil painting, inspired by artists like Waterhouse and John Constable, and contemporary creators such as Jeremy Mann and Greg Manchess. The style is intricate and high in detail, capturing the dramatic essence typical of works trending on ArtStation and CGSociety, with a touch of Makoto Shinkai's Kyoto influence.
