A full-body portrait of a strikingly beautiful woman in a ruined cathedral, reminiscent of a Sister of Battle from Warhammer 40k. She stands confidently, donning cracked and worn steel armor, dusted from the decay around her. The intricate details of her symmetrical face are accentuated with reflective eyes, dark eyebrows, and elegant makeup, including mascara. Her visage is enhanced by a subtle forehead tattoo. The setting features grandiose, ruined marble walls with dust particles dancing in the dramatic, rimmed lighting, highlighting bullet holes and cracks. The composition is in the style of a professional, majestic oil painting, inspired by Waterhouse, John Constable, and other renowned artists, and trending on platforms like ArtStation and CGSociety. Despite the surroundings, her beauty and poise remain the focal point, with no distracting deformities or awkward features, capturing a perfect blend of strength and grace in a high-detail, intricate artwork.
