Rainbow Sky Birthday Card

This design shows a bright sky-blue background with soft white clouds and a rainbow arcing across the top, setting a friendly, lighthearted scene 🎉. Centred near the upper middle, the words “Happy Birthday” appear in large rounded letters filled with multiple colours and edged in white for easy contrast. Around the lettering, shiny balloons in green, red, orange, and teal float upward, their thin curling strings drifting like they’re reaching towards one another. Below, rolling green hills stretch across the card, dotted with simple tulip-like flowers in pink, orange, and deep blue that lean in close like companions in a shared moment. The overall lighting feels gentle and sunny, giving the landscape a soft glow without harsh shadows. Near the bottom, a small reddish-orange snail with a spiral shell inches along the grass, its raised antennae angled towards the flowers as if drawn to their company 🎂. The balloon strings loop and coil above the hills, while the snail sits low in the foreground against the green field.
