You should use this for your intro

I can give you a version without the music too, if you'd like
I actually really like that, it would be much better if you could find a way to make it shorter though (other than just speeding the whole thing up,) 15 seconds is pretty lengthy, especially when a lot of people don't like intros at all
Anyways, I actually really like the style of the video. The only suggestion I would have is that you do some lesser known add-ons and features. Duplicator, Fill-can, and RTB are very common and are easy to figure out quickly, so this kind of video is pretty unnecessary for them. No matter what structure you have for your video, if it's an informative video about things everyone already knows about, people won't watch for long. Try doing some videos on GSF's terrain generator, buildable vehicles, Nexus' command gui, or something like that. That way they will actually be genuinely informative and helpful, and you can probably learn a few things on the way as well.
