Designed with a calm coastal look, this Birthday card centers on a tall off-white panel with softly torn edges that add a touch of texture. Near the top of that panel, “HAPPY Birthday” is placed in deep brown, with “HAPPY” in a classic serif style and “Birthday” in a flowing cursive style. The left side background is muted sage green with a lightly weathered texture, dotted with small five-pointed sea stars and curled shells that cast gentle shadows. The right side shifts to sandy beige with matching sea-life icons, creating a warm-and-cool balance that feels like two friends strolling the shore together 🎉. Soft lighting and roomy spacing keep the layout relaxed, while the repeated shells and sea stars suggest a quiet closeness, like shared treasures collected along the waterline 🎁. The off-white center strip divides the green and beige sections in a straight vertical line, with the sea stars and spiral shells scattered evenly on both sides. Tiny shadowing around the marine shapes makes them look slightly raised against the sage and sand backgrounds.
