关于这个设计

A sunny chest print: a wide horizon line splits the design, with a flat semicircle sun sinking into it and three simple wave curves below. Standing on the sand line are three cute stylized cartoon figures — a woman, a man and a child — as friendly cartoon-avatars standing in for a customer photo (NOT photorealistic), the child holding a sandcastle bucket with a lit candle stuck in the top like a birthday cake. A striped beach umbrella leans in from the right edge. Arched above the sun in a breezy handwritten script is "Birthday Beach Day", and below the waves in small spaced caps sits "SAND, SUN, ONE MORE CANDLE". The three handwritten names "Sienna", "Otis" and "Wren" run along the bottom, separated by two tiny starfish. Ocean teal, sunset coral, warm sand and deep navy on white. Text, each spelled correctly and appearing exactly once: "Birthday Beach Day", "SAND, SUN, ONE MORE CANDLE", "Sienna", "Otis", "Wren". Style: breezy flat illustration with simple geometric shapes and warm summer tones, light and cheerful, high-contrast and print-ready.
