Joyful Swim Birthday Card

This design shows a pool-like scene in wide teal water, viewed from above, where four simplified swimmers glide in neat lanes as if sharing a lighthearted moment with friends 🎉. In the middle sits an off-white banner with “Happy Birthday” centred inside it, outlined in warm orange for a sunny touch. The lettering mixes a flowing style with thicker letterforms, giving the message extra energy without crowding the space. Each swimmer wears orange and red swimwear with dark goggles, and their bodies angle towards the centre as if circling together. Pale blue wake lines trail behind them, suggesting quick strokes and the kind of togetherness you see when people keep pace side by side 🎂. The lighting feels bright and summery, with the calm teal background making the warm colours stand out. Along the left and right edges, the lane borders alternate between red-and-white stripes and narrow multicolor tile patterns made of small rectangular pieces.
