First off, i'm not a fan of the intro. Does "Kaboom" relate to your channel in some way? It looks like you took a scene from a movie or a show, added the "kaboom" in, and added a zoom in on some text. It looks like you used a font that is a slight variation of Times New Roman, just with more rounded edges. That is not a good font to use in your channel.

It seems like you start right in the middle of a conversation. I also noticed that you say "anyway" quite a bit. You said it 4 times in the first minute. Maybe it's just me, but that sort of things annoys me very quickly once I became aware that it's something you use like "uh" for other people. Your commentary about taking out that boss thing was pretty dull. It was just you talking about taking it out. That might be okay for a walkthrough or a guide, but it was not entertaining for a Let's Play. Your voice was also pretty monotone throughout the video.

That's not to say that it was all bad. You are, or at least seem to be, knowledgable of the game. You also seemed to be enjoying yourself. That's pretty important. When someone isn't having fun, it's easy to tell that they're just forcing it.

I stopped at 6:30. I don't want to sound too harsh. But, you did want an honest opinion. That wasn't great. You didn't introduce yourself in any way. Your commentary was very generic. You're voice was pretty much the same tone throughout the video. Because I was curious, I checked your channel You have no thumbnail for the video, horrible tags, and a lackluster description. Overall, it was not good. You have a lot of work ahead of you if you want to be successful on Youtube.
