Designed with a sweet birthday scene, the illustration centers on four round, stylized feathered creatures standing shoulder to shoulder like close friends sharing a private joke 🎉. Two are colored a gentle mint green, one is a calm sky blue, and one is a sunny orange, each with big glossy eyes, rosy cheeks, and tiny pointed beaks turned slightly toward one another. Small crests on their heads and their snug spacing add a tender, companionable feel, as if they’re leaning in together for the moment. Above them, three balloons float upward in soft coral, warm peach, and muted teal, each tied with a thin black string that draws the eye up. The greeting “Happy Birthday!” sits in the upper right in dark lettering, large and easy to spot against the white space 🎂. The background stays mostly white, sprinkled with small star and cross shapes in light gray and muted blue. Beneath the group, a pale ground strip is suggested by faint diagonal gray lines.
