Cream-toned teddy bear rests amid cloud-form balloon groupings, while cylindrical birthday cake featuring white candles anchors right composition. Golden stars and pink hearts scatter across blue surface, complemented by textured balloon hearts suspended overhead. Lighting renders volumetric soft shadows on spherical forms, creating luminous quality throughout scene.
