You seem to have an issue with your audio in the beginning that is making you echo which is pretty distracting and hard to fully listen to. It sounds like you recorded yourself twice and overlapped them instead of deleting one of them. Make sure you only have one mono file. From what I can hear after, I love the soft tone you go in for this. The way you say mighty smile with that whispery tone helps give off that reminiscent feeling. Try playing with varying up your tone and emotions. Put a smile on your face and brighten up when speaking about the fun things about Mrs. Nillimore to give more of a varying delivery rather than have the same, soft tone the whole time.
