You've got a good voice so you can do the narration yourself. And you look decent so you're not going to scare little children away. But you've got the intensity of a hyperactive geek who overdosed on Froot Loops. Don't take this the wrong way. As a proud geek myself I know that this can be intimidating. The other problem with the video is that it looks home made. (Yes, I know that it is home made) This is OK for technical tutorials but not for a sales presentation. Potential customers might think that this is a sign of an unsuccessful company. And they might associate this apparent lack of success with a bad product. Yes, people are shallow. The video contrasts with the professionalism of your website. Your website looks good and professional. Tone your intensity down a bit and remove yourself (and your room) from the video and you'll make your software look a lot more trustworthy.
Another recommendation is to not use your gmail account... sort of. It makes you look like a kid in a basement instead of like the owner of a small software company. But you can use gmail for your domain for free so you can still get the greatness of Gmail with the legitimacy of your own domain.
Good luck.
