So I'm assumming you will be trying to create a shohin out of the lower half. With all the cuts and no taper this is going to take a long time to achieve something spectacular. Luckily you are still young and have the time.
Persoanally I would of left it as is and let it fill out for a year or so and keep it trimmed. Then I would sell it at a big sale somewhere and people would pay good money for it. Then I would go and concentrate on that incredible bougie of yours that has the "Ask the Master" forum in a heated debated. That is a spectacular tree in the making and where any extra time you have is better off spent. Just my opinion.
