Watch out for those T sounds with making them sound like D like in the words Peter and teetered. Start out with over articulating so that you get used to it. Then the more you do it and gradually get a better flow and pace, you'll naturally start to articulate without having to think about it.

Slow down a little bit so that it doesn't sound too rushed. You want to give the audience time to understand and absorb your words. I could also hear some slight hesitation here and there as if you didn't know what to say next and that you were reading it word for word. You want to make sure that you sound confident in what you're saying and that you know exactly what to say next so that it feels more real. Reading ahead takes practice so the more you audition and work on projects and practice, the easier it's going to get. Read out loud every single day to get that practice in. Continue doing tongue twister, exercises, watch shows or movies and mute it, add subtitles and just practice. You want the audience to be able to fully connect and visualize the scene and words. Nice job!
