The sun is shining brightly on this delightful scene of three children playing together in the sand. The two girls are sitting down and busy packing sand into a cake-shaped mound while the boy stands a few feet away, observing curiously. All three are wearing brightly-colored clothes dotted with specks of sand and have sandy hands, as if they just returned from an impromptu trip to the beach. To bring this image to life, use bright, warm colors for contrast and to give the scene a summery feel. The two girls could be in pink and white dresses, with perhaps a hint of blue from the reflection of the sea. The boy, who could be a bit more casually dressed, can don yellows and oranges of the sun. For their sandy creations, use a softer pink and tans for the texture of the cakes.
