Create an NFT-style image of a character with exaggerated facial expressions. The character should have long hair and prominent features such as big eyes and mouth, similar to the style of a caricature. The illustration should be bright and dynamic, with colors that pop and are attention-grabbing. The outlines should be done with simple, clean lines to give a soft and approachable feel to the image. The overall artwork should have a whimsical and playful vibe, typical of NFT art.
