A stunning full-body portrait of a beautiful woman, exuding strength and grace, wearing the attire of a sister of battle. She stands in a ruined cathedral, embodying a serene yet powerful presence amidst the decayed marble walls marked by dust particles, bullet holes, and cracks. Her face is symmetrically detailed, with reflective eyes, dark eyebrows, and artful makeup, highlighting her fierce gaze. Her battle-worn armor is both dirty and cracked, reflecting countless battles. The lighting is dramatic and detailed, with a touch of rim lighting enhancing her majestic aura.

Set against the backdrop of a trending ArtStation and CGSociety style, the artwork captivates with intricate detail. Her forehead bears a tattoo, and she wears a veil and headwear, complementing her steel armor. The scene's lighting enhances the dramatic impact, conveying an intricate, high-detail portrayal of strength and beauty.
