The sound quality as well as your vocal quality are great! What I'd focus on is vocal inflection, as your reading was, for the most part, rather one-noted. This is a children's story, so you should perform it as such. With enthusiasm and attention-grabbing.

This sounded great! I get the impression that you're rushing a little bit throughout the performance; because of it, there are many sounds that you are skimming over. "Peter" "Padderton" "Patterns" etc. feel dull; adding more passion and slowing down a bit will allow you to bring every single word out even more clearly. I did like the consistency from start to finish, and whenever you brought a bit more passion and added a smile to your voice, I could really feel it. Try doing that even more. Great job!
