This greeting card features the words “Happy Birthday” centered in a dark, easy-to-read type, standing out against a pale mint-green background. Around the lettering, a cluster of butterfly silhouettes sweeps in a loose oval, as if they’ve drifted together to encircle the message like close friends gathering for 🎉. The butterflies range from deep teal to light aqua, and their overlapping wings create a gentle sense of closeness, like a quiet, affectionate crowd leaning in. Some shapes appear slightly larger and darker, with soft shadowing that makes them feel nearer, while lighter ones fade back to add depth. The text sits in the middle with ample breathing room, and the butterflies frame it from the upper left through the lower right in a flowing curve. Fine antennae and curved wing edges add delicate detail without cluttering the layout. The overall scene keeps a calm, airy look, with the teal-and-aqua butterflies floating on the mint field like a soft breeze moving through.
