So sorry, had to get to back home to a larger computer screen.
From what can be seen, don’t see a need to push back at this time. The goal, if I recall correctly was to build strength. Looks like the tree is starting to do so, but still needs another year. Would check next June after candle balancing is complete. But thinking another year would do the tree a world of good.
A couple thoughts. Been pondering the concept of critical mass for trees. Nothing new, but in my terms it’s the point at which each bonsai develops healthy, robust, widespread growth through its canopy. Of course it all starts with a healthy, ramified root systems. Visually it a bit different for each species and each tree. One of the indicators is growth spreading sideways, another and perhaps more telling is backbudding to the third level.
When this happens it’s also time to rethink the original style before pushing back, to ensure its validity.
Just a thought.
Finally photos. When taking images for comparison it’s helpful to go back to see the original side views one took in a thread. Then pose the tree at the same pose and viewpoint for follow on shots. This makes comparisons much easier for both yourself and others.
Stay well,
