Create a full-back tattoo design featuring a powerful, intricately detailed dragon in a realistic style. The dragon should cover the entire back, with its body winding and curling, creating a sense of flow and movement. Emphasize the texture of its scales, fierce expression, and intricate claws. Add depth through dramatic shading, with highlights on the scales and wings, creating a bold, dynamic look. The design should be balanced, symmetrical, and visually captivating, evoking strength and mystique
