A devout sister of battle stands in front of a stunning stained glass window, her intricate sci-fi nun armor gleaming. This scene captures her in action, with dust particles floating through detailed chiaroscuro lighting. Her face, symmetrical and detailed, features reflective eyes, dark eyebrows, and soft makeup. The setting is enriched with marble walls, creating a dramatic, atmospheric environment. The painting style is reminiscent of a majestic impressionism oil painting inspired by Waterhouse, John Constable, and others, with influences from Studio Ghibli and Makoto Shinkai. The artwork, trending on ArtStation and CGSociety, evokes a sense of high detail and intricacy. Two characters add depth to the scene, contributing to its engaging narrative.
