Festive Cake Celebration Card

Designed with a soft watercolor look, the illustration centres on a tall slice of layered cake set against a lightly textured creamy white background. The cake rises in four stacked colour bands, moving from warm golden yellow at the top through gentle coral and deep pink to a rich purple base, like a sweet gradient. Thick white frosting drapes over each layer in wavy folds, giving it a cosy, shareable feel like something offered to a close friend at a small gathering 🎂. A slim purple spiral candle stands at the peak, topped with a golden-orange flame that glows warmly. Just below the cake, the words “happy birthday” appear in flowing rosy pink lettering, centred and spaced to sit neatly under the slice 🎉. Faint shadows under the dessert add depth without darkening the airy background. The candle’s flame is painted with a bright core and softer orange edges, hovering above the purple wax.
