Your voice fit perfectly here in my opinion! I think if you slowed down a bit, it would have emphasized that soft and slightly emotional voice even more. My advice is to hone in on that emotional character present in the script and really bring out a performance that makes us FEEL for the speaker. Instead of reading a script, I want to feel like this person is 100% emotionally invested in what he is talking about. Overall, great work here, keep on practicing and improving!
