Well, it IS a cute story. As for the writing itself, I think it's too verbose. I'm not suggesting you reduce the events, scenes or objects depicted. Au contraire, I think you should leave each and every one of them in the rewrites. (Yes, IMO, it should have more rewrites.) But I think you should reduce the words, pare them down to make this sparse. I'm not suggesting minimalism, but more like weeding the garden until the best plants - those most desired - remain. For example, "...added with his imagination and mine" could be simply, "...with some added imagination...". Similarly, "...to come out of his castle..." could be pared to "...leave his castle," or something similar. Your writing style reminds me a bit of mine when I began. It's difficult to reduce the text, especially when your words mean so much to you, but I've found the most effective writing (that with greatest impact) is the one that says and implies more using fewer words.
