I watched a few of your videos.

A couple of things - it seems like you arn't going based of a script or bullet points before you make the movie. There is a LOT of hmm umm aaah and a feeling that you are trying to remember what your next point was going to be.

I'd recommend you take a look at some actual training videos where they talk about the subject, the topics they will cover and then cover each subject - just brings a feeling of structure to it.

Cool idea mate, good luck with your project and hope you have fun with it.
