Generate a detailed Oak Tree centerpiece for a full back tattoo in a black and grey realism style. Integrate an Alcoholics Anonymous (AA) symbol (circle and triangle) and the birth years 1974 and MCMLXXIV into the sprawling, tangled roots. Carve the name Sasha clearly into the sturdy oak trunk, with a detailed Heart icon directly above the name. At the base of the tree, add delicate Flowers. The upper branches of the tree should reach upward to form a clear Cross silhouette, with soft light beams shining through the leaves. Use deep shading and high contrast to emphasize the texture of the bark and veins of the leaves".
