Ken,
We all love you round here and I know for a fact you'll take this in the right spirit.
A client of mine called me recently and said...
"Alan, your a great copywriter but your voice sounds CRAP on your site audio .. REMOVE IT"
Well, no point beating around the bush. I took my voice off right away and have a voice over specialist recording another for me.
Can I be blunt. You looked terrified on the video

and very stiff. Ever seen a Rabbit in your headlights? I would either lighten up or pull in an actor. And to be honest the bit at the end when you point to the left ... left me in stiches with laughter.
I issed a lot of the copy as I just watched you
Or...
Rehearse it. You have a great voice to listen to. Passionate and believable
But ... the production and background was awsome, loved it. Sound good, picture very clear.
How did you add that background, looked great.
