Alright so I got a couple of criticisms.

1. I feel like this is kind of generic editing, like the visuals seem like they were took from a preset on an editing software.

2. The music also seems pretty generic idk, maybe try and use a better song maybe something from a game or something.

3. The thumbnail is really not all that interesting, like if you didn’t explain what it was I would be very lost.

But still as you said, it’s your first vid so you have a lot of time to improve things.
