This design shows a vertical night-sky scene lit by a star-like burst of white light at the center, like a shared moment of celebration 🎉. From that bright core, ribbon-like trails sweep outward in electric teal, fiery orange, calm blue, and magenta, curving as if they’re reaching toward each other. Each trail is made of tiny sparkling dots, and the way they overlap feels like two friends leaning in close during a big cheer. Smaller sparks drift away around the main burst, adding a soft, airy texture that suggests the party is still unfolding 🎂. In the lower third, the words “Happy Birthday” sit centered and easy to read. The lettering glows in a violet-pink neon look, standing out against the deep, dark background. The corners fade into a velvety black, with scattered pinprick lights trailing off toward the edges.
