First off, good lesson, but you wanted some feedback, so here goes
Big point, when you record switch yourself around so that there is light infront of you and not behind you. When you are showing the fretboard, you can't see the strings cause it is too dark. I've noticed this in your other videos. You might want to get a white sheet and hang it up behind you and get a couple of lights and put them behind the camera (maybe take the shades off). And close the curtains.
The other thing is flow. Try rehersing the lesson a few times and record yourself each time and watch it. Might try getting some poster board and writing the script on it and having a friend flip them while you record it.
Also do a couple of takes and then edit to take the best peices, does not have to be done in one shot.
And as has been said before, put up a powertab/sheet music of whole song so that it is easier for us to follow along.
But keep going they are good and informative.
