I'm not going to really comment on the content side if things as I have only given it a quick glance over... but..
Good video quality, this should be the minimum quality that people do their video's in. So thanks for that.
Hosting, great. It's fast, no loss in quality and gives people the opportunity to download and keep it for reference in various formats. Exactly what we wanted.
Now for the negatives,
You go too fast, you type a command and people don't really get a chance to see the command you typed before you have hit enter. Add a little pause of a couple of seconds before you hit the enter key so they have chance to see what you typed so they can replicate what you are doing at home.
You don't really give an explanation of what you are doing or why you are making those selections (what does each part that you selected do and why did you select the ones you did.
If people are to understand what you are doing then they need those things.
So good work on the video's
None of that is a criticism it is guidance for future ones.
Follow that guidance and you could be producing great quality video tutorials that have the potential to teach very complicated material in a simple easily followed and understood manner.
Keep it up
