This card features a tall, multi-layer cake in pale yellow, with horizontal rainbow-like stripes wrapping the base and a glossy blue icing drip along the top edge 🎂. Above the cake, a curved rainbow stretches across the scene, with its ends tucked into two rounded yellow clouds that seem to lean toward each other like close friends sharing a secret. The background is a soft blush pink, sprinkled with tiny stars, dots, and confetti shapes in blue, yellow, green, and pink for a light party feel 🎉. Near the top, the words “Happy Birthday” sit prominently in dark, hand-drawn lettering that stands out against the pastel backdrop. The cake’s gentle shading and smooth highlights make it look sweet and inviting, as if it’s waiting to be sliced and shared. Small decorative marks float around the rainbow and cake, adding motion like a quiet burst of celebration in the air. The blue icing forms rounded drips that hang unevenly over the cake’s edge.
