I'll be honest, I prefer the image one back from the final one. That one still had a lot of starting points, so if you had let it grow out from there, you would have had a lot to choose from for future work within just a few seasons.
From where it's at now, I feel like you've painted yourself a bit into a corner. It may be a corner you really like, and you may have gone there completely on purpose, but your options are undoubtedly more limited now that they were before that last pruning. With these trees, you have the luxury of being able to let them grow out and see how they're going to develop before making final decisions. They grow slowly enough that the worse that usually ever happens is that you still cut off what you were going to anyway, but the trunk looks a lot more developed before you do it. There's virtually no downside to working these slowly once you set an initial direction.
If that were mine, I'd probably let it establish a decent root ball, and then I'd up-pot to something a little bigger, then probably leave it in the bigger pot for about 5 years. You might want to re-pot around year 3-4 (into the same pot), but you may not even have to. Letting it scale up a little will add a lot of character to that trunk, even if you scale it up very slowly to keep your proportions intact.
I'm curious to see where you go with this next - please post updates.
