ネオ・トラディショナル Design a tattoo featuring the letter 'S' in a bold 3D style. The letter should have a metallic or stone-like texture for added depth. A sword pierces through the 'S,' cutting it into two uneven halves diagonally, starting from the top-right quadrant and slicing through to the bottom-left. The sword should have intricate details on its blade and hilt, with a realistic look. The two halves of the 'S' should appear to be sliding apart slightly, with a visible gap where the cut occurred, emphasizing the separation. Add shading and highlights to enhance the 3D effect and make the split look dramatic and dynamic のタトゥーアイデア
