New English YouTube Channel Looking for Feedback

Hello everyone I recently made a new English learning YouTube channel. Its called Learn Casual English and I am trying to help people learn casual English because I believe its the most important step to becoming a fluent sounding speaker. If you could please give me some feedback on my videos that would be awesome thank you!
