nice graphics! I would say connect the vocals together and make a more cohesive impact in the end. dont worry about vocals mixing on top of your text, people can read and listen at the same time (yeah i know who knew..). Right now the vocals seems so separated and far apart that it feels like you didn't have enough of his voice and you just decided to spread it around to fit the video.
also hope you dont mind, splice the intro, the one before 'with tmot'. and make it at 50% or 75% speed, it's too long and not that important to viewers. get right on to the content ASAP or you'll lose views.
this would really be powerful if you had voice over, just imagine it, it would be so different. go to radiodaddy.com that's where i get my voice overs 10-20 dollars or 5 bucks whatever you want to give.
