Sound quality is good. Looks like a unique video idea where you have your own corner to talk in, which is good that you are doing something different. Only problems with that it can be a little bit bland as we are just seeing your back. Also the writing that you have posted on the wall is quite hard to see. Something I'd suggest is instead of hand writing, print out words and images then stick them on the wall as you are talking about. This would give the channel a more professional feel and involve the viewers a bit more. Video length was a bit too long and drawn out for my liking, maybe aim for around 5 minutes to reel more new viewers in, later when you have a larger subscriber base you can lengthen the videos.
Overall really nice idea for a video, good to see something different
