First of all, I love the thumbnail! I think it looks really nice and clear what the video is about,
I want to say... the music is a little too loud, either that or your voice is too quiet so it's a TINY bit hard to focus on your voice..
I think the pacing and layout of the video is really good, the use of video clips, gaming clips and added text are also nice.
It might be nice to add a set of timestamps in your description!
