Spring Floral Envelope Digital Illustration

Full prompt

A charming, tender digital illustration set against a soft pale green gradient backdrop with subtle shimmering stardust particles. The centerpiece is a close-up of an open off-white envelope emerging from a mailbox, overflowing with lush spring blooms including gradient pink tulips, delicate lilies of the valley, and pale blue daisies, each rendered with crisp floral petal textures and soft velvety tactile feel. A dainty swallow with pink accents hovers gracefully above the envelope, which bears the centered inscription '-Spring Diary-' along its front. The entire scene glows with dreamy, diffused pastel lighting, capturing a soothing spring melody.
