Whimsical Cloud Letter Card

This design shows a wide blue sky with a gentle gradient that deepens toward the top, like a calm day made for celebrating 🎉. Across the center, “HAPPY BIRTHDAY” stretches in large, puffy cloud-shaped letters, bright white against the blue. Each letter looks softly formed, with feathery edges and thin wisps that trail off as if a light breeze just brushed past. The message sits horizontally in the middle of the scene, leaving open sky above and below so the words feel airy and floating. The overall look suggests a sweet, friendly gesture—like someone quietly pointing up together and sharing a knowing smile 🎂. Near the lower part of the card, smaller scattered clouds gather along the horizon line, adding depth without crowding the main text. The cloud letters have a cottony texture with subtle sunlit highlights, and a few faint streaks of cloud drift nearby.
