This design features a cartoon character, a young girl with a cheerful expression. She is wearing a large pink sombrero and a yellow dress with a white collar. Her arms are outstretched, and she is smiling broadly. The background is plain white, which contrasts with the colorful character. At the bottom of the image, there is a banner with the text "Happy Birthday" in bold, yellow and blue letters. The style of the image is reminiscent of a digital illustration, possibly used for a birthday greeting card or a similar celebratory purpose.
