How is this yamadori and what should I look out for in the future ?
I think it's has good movement from the base.
The only thing perfectly wrong, which is good cuz it makes it easy to explain, is your trunk heights according to thickness are backwards.
You want the skinniest shortest, and the fattest tallest. This isn't a rule that is easily broken, until you have more than 7 trunks.
The problem you will encounter if you don't flip it soon, is your possible budding area is backwards as well, so the skinny one will grow faster, and the thick one slow, so soon, you will have 3 trunk of all the same size, and lose that favored added dimension to the composition.
The roots won't mind light, but that container will fall apart by the end of May, so I'd duct tape it too!
Or maybe better, get that things rear closer to the center of a more appropriate container so you can continue to enhance the base, and this necessary left roots, that, long, and thick, will give the real impression they've been holding that lean.
Chizeers!
