This was very well written and other than grammatical errors (which have already been pointed out) I couldn't find much fault with it. I would have liked a bit more description but that's something I need to work on, too. This story really captured a child's innocence and the power of imagination. I loved the last line it was absolutely brilliant and you definitely have talent and a wonderful writing voice.
