A full-shot body portrait of a devout Sister of Battle in an intense action scene, featuring a beautiful woman standing confidently in front of a stained glass window. Her face is symmetrical and detailed, with reflective eyes and dark eyebrows enhanced by mascara and subtle makeup. Clad in sci-fi nun armor reminiscent of the Warhammer 40k style, she is framed by marble walls with dust particles floating in the air. The lighting is dramatic and detailed, employing chiaroscuro techniques with prominent rim lighting, casting a majestic, almost impressionistic aura reminiscent of the works of Waterhouse, John Constable, and Jeremy Mann. The overall composition blends the artistic styles of Studio Ghibli, Greg Manchess, and Antonio Moro, trending on ArtStation and CGSociety, to create a high-detail and intricate oil painting. The scene is set with steel and medieval armor elements, adding to the grandeur, capturing the essence of a professional majestic masterpiece while avoiding any distortions or distractions.
