Designed with a muted mint-green background, this birthday card keeps the look simple and airy while still feeling close and affectionate 🎉. Centered on the front, large white “HAPPY BIRTHDAY” letters sit in raised style, with soft shadows that give the words gentle depth. Four rounded balloons frame the message, spaced around it so they feel like they’re floating nearby like friends gathering in. The balloons come in soft gray, creamy off-white, and blush pink, with subtle highlights that make them look smooth and lightly glossy. Thin, wavy white strings trail downward, and extra curved white lines drift across the layout, adding a calm sense of motion like a shared laugh in the air. Small heart shapes in blush pink and light gray are scattered between the balloons, suggesting a tender connection without crowding the design 🎁. The “HAPPY BIRTHDAY” text remains centered and bright white against the mint field, while the balloons and hearts sit around it with plenty of open space and soft, even lighting. Along the edges, the balloon strings and a few floating hearts guide the eye back toward the raised white lettering.
