Overall, I found the narration well-paced and easy to understand. No comprehension problems or anything, and nothing that outright bugged me. (That's always a good sign!)
It doesn't feel all the way professional to me though, and I'm having a hard time figuring out why. It may have to do with the recording quality. I can hear a sort of hissing/hollow effect in the background (or at least, I imagine I do) and the overall impression is a tad tinny.
Also, I noticed that leading and ending consonants of words aren't enunciated as clearly as they could be. This didn't cause a comprehension problem - I could understand each word just fine. But it also didn't feel as crisp and clear as it could have been, and I think those consonants might be part of the reason.
Please note that I am by no means a voice professional, and there's no guarantee that my feedback sound.
