good music, good quality, one thing that might deter some people from watching is at the start when the man is talking but all you hear is music, i get that you do your own commentary over it but the first 5-20 seconds of a video is the most important, if you cant get people intrigued in that first 5-20 seconds than they may not watch the full video, overall i think this is a good video, decent microphone quality, very imformative and you speak about the subject well : keep it up man good luck!
also if you would like to check me out im a gamer, i wont post my link but if your interested my channel name is "Avere Mista" its the only channel that shows in the search so you will find it
