Take your time.

You should add, more mobs, the nether, 1 or few more game modes maybe like, one block, prop hunt, roleplay, etc. New skins, new weapons. I feel like a lot of people would have the same idea or agree with me, having a new ore like netherite. I feel you should hire more devs, artist, coders, admin so on. Maybe a villige or a pillager outposts.
