I love your tone! You also took your time in the PTD script which kept everything clear. If you are unsure of whether or not you said something correctly, it can't hurt to try again from the start of the sentence. Also, the "Oh!" in the BGK script really got me, I totally thought you were about to go back because you forgot something! Very natural. I think you began to speed up a bit in the BGK script, but hey, that was extra credit anyways haha! Overall, great job.

For what it's worth I don't think you sound terrible at all. I do want you to focus on bringing that naturalism to your read. The second read had more of your personality in it which was easy to pick it sounded like you had more fun. Take that approach with both scripts and never forget your audience, your reading for children make sure that you keep them engaged threw out the entire read. Always make sure your articulation overall has the power behind your voice. Still, this was good and nice going taking your time with the script.
