Since this is the front I chose, there probably isn't a reason to rush and kill the tree to root the back side, think I will wait till early next spring and cut the pot away and add a bonsai mix and not disturb the roots, also remove the top few inches till I am just above the roots. Might need to remove some soil from the bottom to get it level.
I build the 4 corner pieces an inch below the top so that when filled with substrate they won't show.
The next choice will be where to lop the top, you can see right at the top of the fence line there is a branch that is more like a leader, it has branches on all sides of it so if I cut just above it should still provide auxins but that is probably 2 years away until all the lower branches have back budded and been shortened.
I want to keep it a rather tall bonsai, since most of what I have now is pretty short.
Very happy with my first $10 Christmas tree haul, think I will buy more "Christmas Tree Permits" this November.
