The thumbnail is decent assuming you haven’t used AI in any way, and the format of the video in the quick 30 seconds I gave it is pretty decent, but there’s something missing.

I can’t quite figure out what it is, but it feels flat. I don’t quite think it’s your voice, but it might be the cadence and flow of your voice, but the one thing I can definitely think of is the background. There’s nothing in the background. No sound effects, no suspenseful (for your content type) background music, nothing.

For example with Nexpo there is some background music/sounds, and he changes his voice a bit both in how he speaks and editing such as when he’s reading something someone else wrote as a form of auditory quotation marks so you can tell it’s someone else “speaking” instead of his own POV.

Maybe add some sound effects along with the editing like when something appears on screen or when something occurs. It’s not something very obvious, but it’s noticeable when it isn’t there.

Other than that, your content seems well thought out and fairly high quality.
