A beautiful woman, exuding elegance and strength, stands confidently with a bolt rifle in front of a stunning stained glass window. Her tanned skin and a delicate fleur de lys tattoo on her face accentuate her striking features. Her sci-fi nun armor is adorned with intricate details, including wax seals, reflecting the Warhammer 40k style. Her symmetrical face is framed by dark eyebrows and highlighted by expertly applied makeup, while her reflective eyes add depth and intensity to her gaze. The setting is a grand hall with marble walls and dust particles glimmering in detailed, dramatic chiaroscuro and rim lighting. The scene evokes the majestic impressionism of master painters like Waterhouse and John Constable, drawing inspiration from the rich styles of Antonio Moro, Jeremy Mann, and Studio Ghibli. The artwork's intricate details and high drama make it a captivating piece, worthy of being showcased on ArtStation and CGSociety.
