Hey dude, it is certainly random. However, the point of a channel trailer is to tell newcomers what you are about. This trailer does nothing for it. Towards the end, it says "HD Gaming Videos" which does give a general view of what your channel is about. That's still a broad view. I looked at the videos and they're mostly about Pro Cycling Manager--something that I'm not interested in. It is an oddly specific thing for a channel that does "HD Gaming Videos."
Rather than that, you can switch up the dialogues a bit if you want to keep the style. Make it more related to the videos you do like "This guy always play this biking game for some reason." Such and such.
It sounds like you don't have a pop filter (that or you do, but you're too close). Yup. :L lol
