Hi Marla,
Good voice, good audio quality.
Some clicks and breathing sounds, not too much. You can work on this, but it’s not a big problem, IMO.
However, there are other issues, that are more of a problem:
In both reads, you are paying too much attention to the original punctuation in the text. Ignore the punctuation, and use your own. Even periods. Ignore them. Do what’s right for you.
Also, there is no change of pitch or tone to keep my interest.
Keep it moving, there were too many pauses.
New employee at Advanced Technologies: I need to hear your excitement about the growing business, and the fact that the job of a new employee is important. Make it sound important.
Museum: It needs to sound exciting about discovering all that cool stuff that the scientists have discovered. And that you, our dear visitor are going to learn about all that. As an aside, I would consider removing the 12,000 visitors since 1953, because that’s a long time, and not too many people.

Wish you success, Marla !
