you are post bonsai - your tree is no longer a model of a tree but a volcano. After hollowing out the center apply vinegar and baking soda solution.Looks kinda like my aquarium.
Also check out the fluity fluits on this backbreaker. Plenty of limbs up and down the trunk to style into a flat top eventualy.View attachment 557763View attachment 557764
