Having heard the first clip: it sounds awesome! Much better than expected. Also weird to be hearing my words read back to me in an epic voice.
Anyway, this is a very good start. I guess I leave this to you: certain parts of the book are a bit redundant and long-winded, so feel free to just edit out whatever parts you think are appropriate. The book wasn't written to be spoken aloud so I imagine more areas than even in print would need to be reduced a bit.
But otherwise this sounds pretty cool.
