How to get better from here in Japanese

Hello, I am already good at Japanese and can speak and understand intermediate level speaking sometimes even advanced. But I think I could better in speaking… since Japanese people are kind they always say "you are very good at Japanese" I know I am not that good 😅
I want to get better and improve my accent so would appreciate if you could point out my mistakes or parts i can do better
Ps. For reference to my Japanese you can check the first video in my profile 🙏🏻 thanks in advance
