I thought at first perhaps your voice sounded a little deeper than normal, but I went and listened to a smidgen of an earlier file to compare - and they sounded basically the same! (We are always our own worst critic!)
It is PL OK of course!
Librivox is a little piece of niceness in the midst of the crazy internet, but I am sure there are those who will be brutally honest if asked to be.

It can be hard sometimes to say the things that sometimes need to be said - although I promise I am being completely honest with my opinion of how this section sounds!
