Trident Maple (from small to medium)

Hello there! It's winter here, and I've been cleaning some trees.
Last year I didn't post an update on this tree after the roots intervention, but I lifted it from the ground and nebari wasn't optimal yet, it was kind of a bum, so I've cutted the roots shorter, fixed the tree on top of a plywood, and took it back to the ground on a raised bed, the base getting wider, may be a good sign!

The idea of a "medium" tree it's probably gone... xD
My goal now is to improve the base and finish the trunk, build a better (and lower) leader on that last section of the trunk.
And I will probably graft the branches in, but when planted in a crate... It's almost time to slow it down a bit.
