I don't think the new video is playing to any of your projects strengths, or likely to win over investors. The main reason for this is that for the most part it's treating the viewers to an up the nose Worms Eye View of your face, and the constant movement of the chair makes everything a bit wobbly. I'm afraid I gave up watching after the first two minutes.
Now, to play to your strengths - you have a voice over guy, so use him to do all the talking. Put that over any in game footage, or stills you may have, giving descriptions of game play elements that might set your game aside from the hundreds of other kick starters out there. Try to resist saying things like 'its going to be cool' or 'hey, this is really awesome' and show the viewers what's awesome about it.
One of the biggest strengths you have at the moment is you respond well to others criticism. If you keep up with that sort of attitude, I'm sure that in time you'll go on to do well. Although I doubt this Kickstarter will succeed as you're asking for a lot of money and not yet giving people enough incentive to invest, I'm sure that you'll learn a lot from the process and hit back stronger and harder the next time.
Whatever happens, finish that game (I'm sure you can make it without financial investment. That's what being a hobbyist game maker is all about!) and keep on listening to the advice of the good folk on this site. They've helped me out a lot - half of the time without even realising it.
