Here lemme give you some feedback:
Looking at your latest video, it seems like you haven't really scripted it. Which is okay, freestyling is fine, I like doing that too. But you have to have an outline and try to cut out some of the uhms and silent moments when you're thinking.
The transitions look pretty weird sometimes... like at 2:30, the cross fade just jumbled up the clips and I found it confusing
Try to cut out parts where you're shrinking back from the camera, so that it's smoother and more flowing.
But your video quality is good, and so is your sound quality.
With that, you just gotta keep making videos! It will take a lot of effort but you'll get there!
