As a 'tutorial' it is not providing a lot of help.
What I see is a video of an arrange screen as a track is progressing, with some random movements here and there.
There are no explanations.
As a 'teaser' it does not do a lot of teasing. It is very static and unexciting.
A tutorial video is indeed a good way of creating a teaser for you studio. But it needs to do a lot more than what your video does for it to be effective.
Nice trailer but a bit too much for a tutorial video, the sound is kinda too cinematic, too dontcha think? For a tutorial, voice over instruction will help. Al1 the best!
