This greeting card centers on a white rectangular sign that feels like it’s been lovingly outlined by hand, with an uneven black border dotted with tiny decorative marks. Across the middle of that sign, the text “HAPPY BIRTHDAY!” sits in large, chunky letters, each one filled with a different mix of bright colors, stripes, and polka dots for a confetti effect 🎉. Surrounding the sign, stylized flowers spill in from all sides, as if they’re leaning in together like close friends crowding the frame for a photo. The blossoms are outlined in black and colored in hot pink, yellow, lavender, orange, and blue, with simple radiating lines that give them a lively, inviting look. Many flowers have sunny yellow centers speckled with small black dots, adding a sweet, affectionate detail like a shared inside joke. Behind everything, a dark charcoal background with light texture makes the white sign and the colorful petals stand out clearly 🎂. A faint shadow under the sign and some flowers adds depth, and the black-outlined blooms form a full border around the central message.
