A majestic and detailed sister of battle stands confidently in front of a vibrant stained glass window, her striking face framed by intricate sci-fi nun armor. Her reflective eyes and dark eyebrows are accentuated by subtle makeup, while dust particles dance in the dramatic chiaroscuro lighting. The scene evokes the grandeur of a professional majestic impressionism oil painting, reminiscent of the works of Waterhouse, John Constable, Atey Ghailan, and inspired by the styles of Studio Ghibli, Jeremy Mann, and Antonio Moro. Marble walls provide a rich backdrop, as the detailed rim lighting enhances the symmetrical beauty of her face. This captivating portrait exudes the atmospheric elegance found in trending artworks on ArtStation and CGSociety.
