I don't know if this was your intention, but I thought this was a really clever way of interpreting the grand expectations that come with a term like "kingdom". I remember when I saw that was the prompt, I couldn't really wrap my head around a way to make something so colossal work for a short story, but you nailed it! Not only did making the story about a kid and their toys shrink down the scale, the character's own imagination still managed to stay true to the epic storytelling you'd expect from a prompt like "kingdom". Really smart stuff!
