A full-shot body depiction of an exceptionally beautiful sister of battle woman holding a bolt rifle, positioned in front of an intricately designed stained glass window. She has tanned skin adorned with a graceful fleur de lys face tattoo and wears armor embellished with wax seals. Her face is detailed and symmetrical, with reflective eyes framed by dark eyebrows, enhanced by subtle mascara and makeup. The sci-fi nun armor she wears is reminiscent of Warhammer 40k style. She's set against marble walls, illuminated by dust particles floating in the air, with detailed, dramatic chiaroscuro lighting. This image is rendered in a majestic impressionistic oil painting style, inspired by Waterhouse, John Constable, and contemporary artists like Ed Blinkey, Atey Ghailan, Jeremy Mann, Greg Manchess, and Antonio Moro. It captures the essence of trending artwork styles on ArtStation and CGSociety, featuring intricate, high-detail, and dramatic elements, reminiscent of the visual storytelling of Studio Ghibli and the atmospheric tones of Makoto Shinkai. The composition focuses on quality and artistic integrity, celebrating beauty and strength.
