Create an illustrated poster of New York City with a girly and retro aesthetic. The artwork should feature whimsical hand-drawn elements with a sweet and playful touch. Include iconic New York landmarks such as the Statue of Liberty, Empire State Building, and yellow cabs, but interpret them with a feminine twist--think pastel colors, soft lines, and decorative motifs like hearts and stars. The landmarks should be simplified, not overly detailed or realistic, capturing the essence of the city in a charming and lighthearted way. Add a skyline silhouette in the background with a sprinkle of retro elements such as vinyl records or classic sunglasses. The overall feel should be airy and not too busy, inviting viewers to a New York that's seen through the eyes of a dreamy, stylish girl from a bygone era.
