Redstone Tutorials

Hello, I have recently uploaded a video showcasing the 3x3 piston door. In the tutorial, I explain how the door works and how to build similar doors like it. I intend for my tutorials to teach the viewer and not show them a step by step tutorial without any context. Can you give me some feedback on how I did as I want to be more helpful in making these videos? Thank you for reading this, here is the link: https://www.youtube.com/watch?v=Vl_UPQ0dUnA&t=3s

I also do Lets plays so you can check those out if you feel like it.
