I’m going to give you some different advice.
DON’T Try to make this into a literati. At least not for the near time frame. It’s just not old enough.
You see, literati trees are meant to depict not just “mature” trees, but “elderly” trees. Trees that have experienced storms, floods, draughts, winds, heat, cold, etc. They have old bark, old scars that have healed, scars that haven’t healed, evidence they have outlived their peers...
You have a young, unblemished tree. No kinks in the trunk, just a stub up in the apex. It just doesn’t have any character. Yet.
So...
My advice is to style this as a tall slant style tree. Try to develop nice branching, in the appropriate places. Give the tree time to grow, mature, experience life a bit.
Then, maybe 20 years from now, it will be ready to restyle as a literati!
I’m doing the same thing with a JWP. I “see” it’s future as a pretty nice literati, but my tree is only about 20 years old, and the bark is still the smooth grey bark that young JWP have. For niw, I’m developing it as a slant while I’m waiting for mature bark:
