I'm not the most qualified considering I plan on to also make a post soon also asking for feedback to improve my own anime content voiceover which I have little experience with. However, I think I see where your concerns stem from considering that your voice is unique and different compared to other more stereotypical anime youtuber voiceovers, but I'm here to say that I personally find that aspect charming and I think your uniqueness helps you stound out in a positive way. You come across as someone excited to share your passions which in turn gets me engaged personally.
I think the voice quality and clarity is fine, only very slight and nit-picky improvements where you slur words together occasionally. Like at 6:51 of your last link. It almost sounds like you say "....shit & tone" when I know you meant "....a shift in tone"
Also I love your funny edits 👌
