A stunning full shot of an enchanting woman in a sci-fi nun armor, emblematic of a sister of battle, poised with a bolt rifle before a radiant stained glass window. Her tanned skin highlights the intricate fleur de lys tattoo on her face, complemented by armor accented with wax seals. She possesses a symmetrically detailed face with reflective eyes, dark eyebrows, enhanced by mascara and subtle makeup. The setting is enriched by marble walls that catch dust particles, creating an atmosphere graced by detailed, dramatic lighting which casts captivating rim and chiaroscuro effects. This composition is reminiscent of a professional, majestic impressionism oil painting inspired by masters like Waterhouse, John Constable, with a touch of fantasy akin to Studio Ghibli, and modern influences from artists such as Jeremy Mann and Greg Manchess. The artwork thrives on its intricate, high-detail Warhammer 40k style and is emblematic of trending pieces on ArtStation and CGSociety, evoking the atmospheric beauty of Makoto Shinkai's Kyoto setting, executed with artistic precision and grace.
