Whimsical Celestial Birthday Card

Designed with a calm pastel blue background, the illustration lines up three friendly sky-themed characters like close companions sharing a quiet moment 🎉. On the left, a crescent moon in soft golden yellow stands on thin black stick legs, with tiny black dot eyes and peachy cheeks that read like a shy smile. Next to it, a creamy yellow five-pointed star mirrors the same simple face, leaning into the group through its close spacing. On the right, an olive-green round planet with a ring wraps around its middle, and its gentle expression matches the others, as if they’re trading supportive glances. The artwork uses flat colour shapes and clear dark outlines, keeping everything easy to read and light on detail. Near the bottom, the message “YOU’RE STELLAR” sits centred in a casual handwritten-style font, drawn in dark lettering that stands out against the blue. The moon, star, and ringed planet are arranged in a neat horizontal row, with their small black legs and faces evenly aligned.
