Birthday surprise in a box

This design features a black-and-white tuxedo cat perched inside an open cardboard box, topped with a red party hat and wearing a wide-eyed, curious expression that gives the card its endearing charm. The soft pink background is scattered with hand-drawn confetti and ribbon streamers in blues, oranges, yellows, and purples, adding energy and festivity without crowding the central image. Visible pastel and pencil texture runs throughout the piece, from the cat's fur to the grain of the cardboard box, lending it a tactile, hand-crafted feel rather than a flat digital look. "Happy Birthday" appears in bold red block lettering across the front of the box, keeping the cat as the focal point while making the occasion clear at a glance.
