I’ll make it a bit easier for you to understand.Your choice. You didn’t mention the intended size of your final Bonsai
Each extra branch will bulk out the node and below. Keeping extra wheel spoke type branches is how inverse taper occurs... which it seems you are beginning to run afoul of from the photos.
Pruning to two will start the tapering process.

The appearance of inverse taper is due to the 2-D photo. There is actually no inverse taper at the base.I'd would layer it a the line because the inverse taper won't disappear soon.

Benefits of starting it off on a tile. Will change the planting angle as I develop it in the future, this is just a grow out pot to get some good roots back on it again.Great because the flare above the roots is really nice.
