If I had stumbled on to that video randomly, I honestly wouldn't of watched passed the first few seconds. The intro goes on far too long and it looks unprofessional. If you don't have the funds to hire someone to make an intro for you, I'd suggest trying to make one similar to the original Glass Reflection one as it only lasts about five/six seconds, rather than 14/15 seconds and it's simple.
As for yourself, I'm happy to see you have your stutter under control. I know it's a hard thing to do, but try to not do as many hand gestures.
Although I will admit, I though that this video would of covered stuff about yourself (how long you've been watching anime etc...) rather than simply informing viewers that you'll be doing reviews. I don't think it helps that you have removed all your other videos, so a lot of new viewers won't know about yout large collection, favourite animes etc...so it might not entice them to return.
If I was you, I would re do this video and talk about yourself, I know it's a hard thing to do, but cover basic things like
1) How long you've been watching anime
2) What was the first anime tv series/movie you saw
3) How large your anime collection is
I feel that if they knew some of that information, they will want to know more about you and want to see more videos.
