Render a clean, high-resolution image of a 3D high-relief sculpture featuring the Blessed Virgin Mary crowned with a halo, standing with an open gesture. She is surrounded by four angelic figures in prayer and reverence. The relief is framed with a thin beveled border and presents balanced symmetry. Use a soft white or stone-textured material and slightly angled lighting to bring out the folds in her robe and the detail in the angel faces. Background should be neutral to dark, allowing the model’s detail and form to stand out. Emphasize the calm, regal posture of Mary and the harmony in the composition.
