I'm sorry, at this point I can't not say anything to that. You obviously try really, really, really hard to get this thing going for you, but at least put some conceptional effort in your videos, not just clickbait titles, like "UX/UI Animation", for something that is without a doubt UI.

If it boils down to it, you are just filming yourself while you look at a website. It is not a "Case Study", but you advertise it like it was. Of course people are gonna be a bit pissed. A bit of basic content strategy would maybe help to prevent that. Never advertise something that you are not offering.

And a word of advice from someone who is also german-speaking: look up how words are pronounced. Review != [ref.juː], but [rəˈvjuː]. Maybe write your text before you speak into the camera, so you don't mix up words or your grammar, if you speak in a language that you are not comfortable with.

I'm really disappointed this isn't a review of the app itself not the site.

Not sure what your background is, but I expected something totally different. A bit more structured. My favorite review method is heuristic evaluation.
