oh, I see, it's an good form of practice. But there isn't very many people trying learn Portuguese. It has a lot of rules and they get tired. So it isn't too easy to find someone that is really focused on learning.
In terms of YouTube channels, I should watch Brazilian stuff. I have been watching "the Korean Englishman." lately. They are British and speak Korean. They do videos in both languages. The comparison videos between US and UK English, by them or others, might be useful to you.
