A full shot of a devout Sister of Battle in action, standing confidently before a stained glass window. Her face is symmetrical, detailed with reflective eyes, dark eyebrows, and subtle makeup. Clad in sci-fi nun armor, the setting is a dramatic scene inspired by Warhammer 40k. The environment features marble walls, with dust particles visible in the detailed lighting. Rim and chiaroscuro lighting enhance the dramatic effect, as the perspective comes from above. The artwork embodies a professional, majestic impressionism oil painting style, influenced by Waterhouse, John Constable, and artistic touches from Studio Ghibli, Jeremy Mann, and Greg Manchess. The work trends on ArtStation and CGSociety, showcasing high detail and intricate elements. The painting reflects the influence of Makoto Shinkai Kyoto, avoiding low resolution, blurry effects, and poorly drawn elements. The composition maintains harmony, avoiding excess or disfigurement, resulting in a crisp, clear image with skilled anatomy and balance.
