Sorry, I just noticed this comment. I know you probably won't see this, but that's not what I meant!
What I wanted to write and the reason why I noticed the accent was not because it was bad, but because I'm also Polish, so I am especially sensitive to Polish accents (and I hate hearing myself speak foreign languages, so there's that)! The same way, for example, Swedish speakers hate hearing their own countrymen speak Swedish! I didn't mean for it to be taken so seriously!
Also, IMO, videos which are voiced by their creators sound better, more genuine. I'd honestly prefer it if you were to practice your pronounciacion just a bit more and the videos would be perfect!
