I'm almost positive he means the left. Definitely seeing improvements every time you give it a shot, so keep at it until you love it, you'll get there, you're already quite close. Generally speaking, rock groups should be odd numbers. This isn't ALWAYS true though.
BTW, 120H is my favorite non-special order ADA tank, amazing dimensions. I'm jealous.
If you remove the 4th rock from the left, I would slide the two right most rocks to the left a bit so the gap isn't weird. I think the result would be pleasing and slightly off centered to the left side of the tank.
Just one idea though, working off what you had. Im not sure of your process, but if you follow Amano's outlined steps iwagumi tends to be easier. Generally place the main stone, then the supporting stone. Then work from there.
Here is one more try, i changed it all, the left side works for me, but the right seems dull. i am going to stop bothering you guys with this stuff, ill continue to practice until i get some that i like, I will be using different stone on my 120. i plan to use Manten stone or petrified wood
absolutely, i am making another one for the 60P, it helps to own a custom furniture and cabinet shop. I will gladly build stands for whom ever needs one. They are just not a budget stand. I can also help with the design if need be. what you do not see on this stand is that it can be leveled with out the use of shims, it has 6 leveling legs, that i also built, that can handle over 600 pounds each.
