Useful Tutorial
You give some very good tips and it's all laid out very well, but you didn't have a section on fully tweening animations (which believe me, can be done well).
Also, I wasn't convinced by your lip syncing method, and it was a fairly brief nad vague explanation. As far as I'm concerned to do it accurately you need to actually look at your mouth in the mirror as you say the line.
But, overall it's a good, useful tutorial
