Playful Little Monster Siblings

Create a vertical whimsical family-life illustration in translucent watercolor and paper-cut collage style, showing two small children as deep cobalt-blue silhouettes transformed into playful little monsters. The older child, about {argument name="older child age" default="3 years old"}, is large on the left-center, barefoot, wearing a short-sleeve shirt and shorts, one knee lifted high as if stomping or dancing, mouth open in a roar, both hands raised like claws, with two small white devil horns and a long curled monster tail extending left. The younger child, about {argument name="younger child age" default="almost 1 year old"}, stands lower right, much smaller, barefoot, wearing a frilly romper, arms raised, looking up at the older child, also with two small white horns. Use a bright backlit white-to-aqua background filled with energetic blue splashes, bubbles, paint droplets, jagged comic burst shapes, and tropical leaf silhouettes around the edges. Include exactly 8 distinct playful surrounding objects: 1 red spiky cartoon monster near the upper center-right, 1 yellow sun with long rays in the upper right, 1 blue-and-orange water pistol on the right, 1 yellow ghost monster at mid-right, 1 red starfish at lower left-center, 1 pair of light blue toddler shoes at lower left, 1 watermelon slice in the bottom left corner, and 1 dark blue spiky monster head near the bottom center. Add leafy shadows in dark blue at the top left, top right, right edge, and bottom left for a summery outdoor feeling. Keep the children mostly silhouette-like but with soft rim light and readable profiles; make the overall mood chaotic, joyful, tender, and nostalgic. Add a small handwritten artist signature and date {argument name="date text" default="July 20, 2026"} in the bottom right. No other text, no photorealism, no harsh outlines, no extra children.
