I’ll have to give it a closer look when I get a chance. At first glance, I didn’t see anything resembling an informal upright, so I’m wondering if something about the 3D shape was misleading when seen as a 2D photo, but it’s also possible that I just missed it as I wasn’t studying it closely. I was going to take a closer look this afternoon, but nature had other plans and it is now raining.View attachment 555677
I think your tree is in the middle. All the exterior can be removed so that the stellar trunk line the tree is giving you can be utilized and shown off. You can make it jagged or smooth, either way.
Currently it has kind of a spaceship feeling. I suppose you could use 1 side of the tree, tilt it for a repot and utilize as cascade but it would be a tremendous waste of a trunk line that already exists with the tree as an informal upright.
