Designed with a calm mint-green background, this birthday card centers a large “HAPPY BIRTHDAY” message in white sans-serif letters with a long, soft shadow stretching to one side. Around the words, several round inflatables float near the edges in blush pink, gentle gray, and creamy off-white, giving the scene a light, friendly energy 🎉. Each inflatable has a faint sheen and a thin, dark string that hangs down, adding a touch of realism. The spacing feels balanced, like friends giving each other room while still staying close, with the shapes loosely framing the greeting. Subtle shading beneath the letters and the inflatables suggests diffused light, adding depth without making the design feel heavy. The text stays centered while the inflatables sit mostly along the perimeter, guiding your eye back to the middle 🎁. A softly wavy line in a slightly lighter mint tone loops around the layout, encircling the message and floating shapes.
