Great effort ! Keep trying. You have a lovely intonation. My recommendation would be to try and practise THE sound. Try to soften the hash Z or DZ sound. I always recommend to stick a tip of you tongue out and gently bite while you let the sound out.

What you have done is very good practice for speaking fluently and pronunciation. I also recommend that you do shadowing. This video explains the process and gives examples. https://www.youtube.com/watch?v=-qZ7L7sWLmQ&ab_channel=socooleyEnglish
