Two things: 1st, did this book come out & how do I get to read it? :-)
2nd, if you re-do this or on any future teaser or trailers, let the text run longer so people can actually read what it says. I read fast & have been a speed reader all my life & yet it was still too fast on several of the text blurbs. Make the video a bit longer even if you have to use blank screen or free common license youtube stuff so that the text can be read by people who need the time to read it, otherwise the quality was better than your comment lead me to expect, stop being so hard on yourself, this is great for uploaded video over broadband. Kudos!
