I do think so voice made your video feel less natural as well. Just be confident and use your true voice! As there’s no one care about if your voice is “good or bad”, but they only care about if your video is interesting or not. In my eyes, they’re really interesting.
Here’s also another tip for you: balance the volume of your video. I’ve noticed you like to make some memes sound effects in your video. This do made your video more funny, but also sometimes it’s just too loud. Try to reduce the volume of sound effects to make sure the volume is balanced.
And if you like to find a teammate, I’m interested in recording with you. But only if you can do voice chat during the game.
Good luck!
