Happy Zigzag Birthday Card

This card shows six floating balloons gathered closely together, like friends leaning in for a group photo 🎉. Each balloon has a different look: one is red with white polka dots, another is orange with a yellow sunburst, and another is green with zigzag stripes, with a few more patterns filling out the cluster. A thin white outline traces every balloon, giving them a crisp edge against the smooth aquamarine background. Slender, dark strings drop from the balloons and guide your eyes down towards the message, tying the whole scene together like a gentle embrace. The greeting sits in the lower third in thick white letters with a slight raised effect, standing out clearly without feeling heavy. Soft highlights and small shadows make the balloons look glossy, as if they could be touched, adding a sweet, celebratory mood 🎂. The aquamarine background stays solid and calm, letting the colourful shapes and the bright white text take centre stage. The strings hang straight down in dark lines and end just above the large white message near the bottom.
