Create an NFT style illustration of a caricatured man’s face. The face should be very expressive with a big, friendly smile and exaggerated features like a large, round head, small ears, and a shiny bald top. The eyes should be small but gleaming with joy. The illustration should be bright and dynamic, with bold, vibrant colors. The entire figure should be outlined with simple, soft lines, giving it a gentle and approachable feel. The background can be a soft gradient of sky blue to represent a cheerful day.
