It's alright. It basically tells us what paints to use and not much else. Vocals would be good (or text, to not clash with the music) to say things like "I put the red mix here, because this and that", because a video of just you painting is not that helpful to people, if I'm honest.
Another thing that would make your tutorial slightly more credible would be you showing the finished results of the model after it's done. In the beginning or in the end of your video. Or both.
Other than that, good music for a tutorial. Great picture quality. The grey-white background is excellent.
Good job, man
