Metuselah potted

Well, this is Metuselah in the pot. This is my biggest tree, and, I think, it's little too big. But, what does it mean "too big"? Now it measures cca 140cm from base to the top of the green mass. It is obviously a kind of literati cascading tree. This curve on the first picture is a cascading part. Probably, in the future, there will not be any green higher than that curve. On the contrary, the tree will cascade back towards the ground and future crown can be positioned in the middle part of the trunk, or, at highest, in the upper third. That will result with the tree 80 centimeters high, or even less. Only high positioned curve will be at the highest point. The bark on the curve is fantastic and old, so that can be very interesting attention spot. Much shari on this tree is obligatory in final design because, it has already rotten core and many stubs left from cutting dead branches.
Nebari is almost 50-60 cm wide. The tree was collected with good root system and I'm not too affraid if Metu will survive.
I believe this tree is old.
