(Re)starting a Youtube Channel and asking for feedback

Hey there guys:) So I thought about this for some time and I decided to just go with it and post the link to my youtube channel here:

If you could give my any feedback on my newest (and, if you wish, older) videos, I would be really glad. Also, if you wanted to sub to my channel to see it grow even further, I'd also appreciate it. Don't look at this at some kind of desperate self advertisement, but I just wanted to know what you guys think of my newest content and how I could improve it. Thanks already :)
