Create a detailed 3D character of Jay Gatsby from The Great Gatsby. He should exude wealth, charm, and mystery, dressed in a dapper 1920s tuxedo with peak lapels, polished shoes, and a pocket square. His slicked-back hair and confident smirk should reflect his enigmatic personality. The character should be well-groomed, with refined features and expressive eyes that hint at both ambition and longing. Include accessories like a gold signet ring and a champagne glass in hand. He should stand in a confident yet welcoming pose, as if preparing to host one of his legendary parties."
