Niños chibi jugando con pelotas de ejercicio

A cute, chibi-style anime illustration depicting 3 children playing on large fitness balls in a cozy living room on a rainy day. The composition centers on a child in the foreground, hugging a blue yoga ball, with messy medium-length black hair, large purple eyes, a slightly sleepy and pouty expression, wearing a black T-shirt and olive-colored work pants, barefoot, leaning forward with arms resting on the ball. To the left is a child sitting on a pink fitness ball, with short black hair tied into small, low pigtails, wearing a white T-shirt with small black and red graphic logos, olive-colored work pants, and barefoot, with hands placed on the ball. Render the face with a soft, square blur mask covering the entire facial area. To the right is a child sitting on a yellow fitness ball, with fluffy blonde short hair, bright orange eyes, a radiant smile, arms outstretched in excitement, wearing a white T-shirt with the text {argument name="shirt logo" default="AIFEK"}, olive-colored work pants, and barefoot. Use a warm, sunny indoor environment with a large window in the background, multiple lush green indoor plants, wooden shelves, framed plant wall art, plush toys including a teddy bear and a green frog, colorful stacking toys, and interlocking soft-toned foam floor mats. Make the room feel soft, safe, fun, and cozy, employing diffused sunlight, soft shadows, clean anime lines, soft painterly shading, highlights on the fitness balls, and highly appealing chibi proportions with oversized heads and expressive faces. Use bright, healthy colors and a refined modern anime illustration style.
