Minimalist children's book cover illustration featuring a small boy standing at the center, looking up with wide eyes, chin up. Great perpective from top to the bottom. He is surrounded by tall, towering walls on either side, creating an intense perspective with the vanishing point converging at the center where the boy stands causing a feeling of smallness and loneliness. The overall composition is simple yet powerful, emphasizing the boy's sense of scale and the vastness of the space around him --cref <https://s.mj.run/4KLObHzZB3U> --cw 10 --niji 6
