Compact tattoo (~15 cm diameter) for the upper back…

Design a compact tattoo (~15 cm diameter) for the upper back, centered just below the neck. The central element is a golden ratio spiral, and it is integrated with the oval floor pattern of Michelangelo’s Piazza del Campidoglio. Incorporate the 12-pointed star and geometric paving pattern that surrounds the equestrian statue of Marcus Aurelius, using these classical shapes as a structural frame around the spiral. Emphasize symmetry, perspective, and mathematical harmony, blending the spiral naturally with the star and paving lines. Use fine linework, painterly shading, and subtle classical textures, ensuring clarity and elegance at small scale, while highlighting both the spiral and the Campidoglio motifs in a cohesive, visually striking design.
