Art style: Pixar-like 3D.
Full-length view, the entire figure visible from head to feet, lying happily upright-propped on a soft padded play mat, correct orientation, centered — a cheerful one-month-old baby boy. He has a round, chubby face with plump rosy cheeks, smooth soft baby skin with a warm light tone, big bright sparkling dark eyes, tiny button nose, and a wide toothless open-mouth smile with dimples. His head is topped with a wisp of fine soft dark hair. He has a soft rounded body with adorable rolls on his arms and legs, tiny curled fingers, and small bare kicking feet with little toes. He wears only a clean, snug diaper around his waist. His pose is playful and joyful, little arms reaching up, legs bicycling in the air. The bright, cozy pastel nursery fills the sides with plush toys and soft blankets.
