A full-body portrait of a stunning warrior woman, resembling the epitome of beauty, stands before a radiant stained glass window, holding an ornate bolt rifle. Her tanned skin glows under the lighting, accentuating a delicate fleur de lys tattoo on her face. Her armor, adorned with wax seals, reflects the sci-fi nun aesthetic of Warhammer 40k, complete with intricate details and a balanced symmetrical face. She has reflective eyes framed by dark, expressive eyebrows enhanced with mascara and subtle makeup. A blend of chiaroscuro and dramatic lighting, set against marble walls, creates a majestic impression as dust particles dance in the air. The scene is painted in the style of master artists like Waterhouse, Constable, and Ed Blinkey, with a touch of Studio Ghibli's whimsy, and the bold brushstrokes of Jeremy Mann and Greg Manchess. This artwork, trending on ArtStation and CGSociety, captures a high-detail, dramatic moment with nods to Makoto Shinkai's Kyoto landscapes, all in a professional oil painting style without unnecessary embellishments or distortions.
