I’m impressed! You can hold your notes, you have good control in your higher notes, you can belt. This is what a lot of people strive to achieve (myself included), but often people like us forget that you can’t just throw a roof on some concrete and call it a house. You need a strong foundation to help the house stand.
with that being said, practice enunciating vowels like EE, AH, OH, and OO. Try it at all volumes, try it singing high and especially while singing low because you can sing. You just have to tune your instrument. You already have the house, just lay down some concrete and some solid pipes my guy!
