This design shows a large neon-pink heart centered on a deep inky-black background, with visible brushlike texture that makes it feel lively and a little unruly in a sweet way 🥰. Inside the heart, the words “Happy Valentine’s day” sit across the middle in smooth white lettering, standing out clearly against the pink. The rounded letter shapes soften the jagged edges of the heart, like a gentle note tucked into a loud, happy gesture ❤️. The black backdrop heightens the glow of the pink and white, giving the whole scene a night-sky contrast. In the bottom right corner, a tennis ball in yellow-green with crisp white seams adds a fun, specific detail, as if the card is winking at someone who shares that hobby. The ball slightly overlaps the lower curve of the heart, creating a cozy little connection between sport and romance. Small white dots are scattered around the text like confetti or tiny stars, floating near the center of the card.
