A full body shot of an enchanting sister of battle, a woman with tanned skin and a fleur de lys tattoo on her face, stands confidently with a bolt rifle in front of a colorful stained glass window. Her sci-fi nun armor is accented with wax seals and has a detailed symmetrical face. Her reflective eyes, framed by dark eyebrows and enhanced with mascara, captivate attention. The dramatic chiaroscuro lighting highlights her features against the marble walls, with dust particles floating in the air. Inspired by the majestic impressionist style of Waterhouse, Constable, and modern artists like Jeremy Mann and Greg Manchess, this scene is reminiscent of a majestic painting that blends the dramatic essence of Warhammer 40k with the intricate detail trending on ArtStation and CGSociety. The atmospheric lighting and detailed scene evoke a sense of awe and grace.
