A majestic full-body depiction of a captivating woman garbed in intricate sci-fi nun armor, standing boldly with a bolt rifle in front of an ornate stained glass window. Her tanned skin glows under detailed dramatic lighting that highlights a fleur de lys face tattoo and wax seals on her armor. Her symmetrically detailed face is framed by dark eyebrows and makeup, with reflective eyes adding intensity. The scene is reminiscent of a professional impressionistic oil painting, blending influences from Waterhouse, John Constable, and Studio Ghibli. The ambiance is set within marble walls as dust particles dance in the chiaroscuro lighting. This Warhammer 40k style image is trending on ArtStation and CGSociety for its high detail and intricate design, capturing the essence of a battle sister in a beautifully intense moment.
