The words 'happy birthday' are set in a loose, rounded cursive and rendered as puffy, inflated tubes, stacked in two lowercase lines at the center of the frame. Warm ivory letters carry soft highlights along their glossy tops and dusty-rose shadows in the gaps between strokes.

Soft light from the upper left gives the lettering gentle volume against a smooth, matte pink backdrop, with generous empty space around the phrase. There are no other figures or decorations.
