This card shows a turquoise swimming pool scene from above, with a soft sense of closeness as four relaxed swimmers drift on their backs like friends sharing a quiet moment before the party 🎉. In the center, a cream, cloud-shaped banner holds the words “Happy Birthday” in dark lettering, surrounded by a thin golden outline. Two swimmers appear above the banner and two below it, arranged evenly so the layout feels balanced and calm. Each figure has pale skin, a red swimsuit, and a bright yellow swim cap, and their faces tilt upward with an easy, content look. Small white ripples circle their bodies, suggesting gentle motion and a peaceful float. The pool background is a smooth field of blue-green color, giving the scene a fresh, summery feel that pairs nicely with a birthday treat like 🎂. Along the left and right edges, vertical lane dividers repeat in red, white, and blue segments, framing the water like neat borders.
