This design features a vibrant and celebratory birthday theme. At the center, there's a large number "7" in a bold, blue font, which is likely the age of the birthday person. Above the number, there's a yellow crown, symbolizing royalty or a special occasion. To the right of the number, there's a blue starfish, adding a touch of marine life to the theme. Below the number, the word "Birthday" is written in a cursive, yellow font, reinforcing the celebratory nature of the image. The background is white, which helps the colorful elements stand out. Scattered around the central elements are small blue bubbles, giving a playful and festive feel to the overall design. The bubbles could represent joy, excitement, or the celebration of the birthday. The overall design is simple yet effective, conveying a sense of joy and celebration associated with a seventh birthday.
