A full-body portrait of a striking sister of battle, posed dynamically, in front of an intricate stained glass window. The woman has a symmetrical face with reflective eyes, dark eyebrows, and subtle makeup. Her sci-fi nun armor is beautifully detailed in the Warhammer 40k style. The setting includes marble walls, with dust particles illuminated by dramatic chiaroscuro lighting, adding to the scene's depth. The scene is inspired by the majestic impressionism of Waterhouse and John Constable, mixed with the vibrant storytelling of Studio Ghibli. The artwork, akin to that of Jeremy Mann, Greg Manchess, and Antonio Moro, is detailed and trending on ArtStation and CGSociety, capturing an intricate, high-detail, and dramatic aesthetic reminiscent of Makoto Shinkai's style. Despite the complexity, the art maintains clarity and avoids unnecessary elements like distorted anatomy, ensuring a refined and cohesive portrayal.
