Cosmic Birthday Balloon Card

Designed with a cosmic birthday scene, the artwork centres on a huge glowing orb that looks like a planet but reads as a balloon 🎉. Its surface blends deep orange and warm red tones, and the words “HAPPY BIRTHDAY” sit across the front in chunky light-blue lettering with a raised look. A thin string drops from the bottom of the orb, gently grounding it and giving the scene a cosy, shared-celebration feel 🎂. Behind it, the sky fades through deep indigo and rich blue, scattered with tiny stars that sparkle like quiet little winks between friends. Smaller round planets float around in orange, pink, blue, and violet, each with delicate rings that echo the main orb and add a soft sense of togetherness. A bright comet streaks across the upper left, like a quick dash of excitement cutting through the calm. Along the bottom edge, layered cloud-like nebula shapes roll in pink and lavender gradients, forming a soft border beneath the floating worlds.
