Tranh Tô Màu Em Bé Đi Khinh Khí Cầu

A clean black-and-white printable coloring-book line drawing on a wide horizontal white canvas, centered on [a cheerful child riding a hot air balloon]. The hot air balloon envelope is large and rounded with vertical stitched panel lines and a curved bunting garland wrapped across its lower half featuring exactly seven triangular pennants with alternating plain and dotted patterns. Beneath the balloon, a small woven basket hangs by two suspension ropes, holding a smiling child wearing a brimmed hat and scarf, waving with one arm raised. Surrounding the balloon are exactly four puffy cartoon clouds: one small cloud in the upper left, one large cloud in the lower left, one medium cloud at mid-right, and one large cloud in the lower right. Add three simple flying bird silhouettes shaped like loose curved V marks (two to the left, one to the right). Child-friendly, rounded proportions, consistent medium-weight smooth black ink outlines, minimal interior details, generous blank white space, no background horizon, no colors, no shading, no text, and no watermarks.
