This design features a graphic of a star with the words "Happy Birthday" written in a cursive font across the center. The star has a simple, geometric design with a five-pointed shape. At the bottom of the star, there are three balloons, two of which are black and one is white. The background of the image is plain and does not distract from the star and the birthday message. The overall style of the image is clean and minimalistic, with a clear focus on the birthday greeting.
