Wel,, say that when it flowers.. Flowers don't reduce.
These also dislike container culture--tend to be a bit temperamental in pots, are prone to root rot and as you can see push leggy, mostly unattractive growth.
It's normal to be a bit enthralled with new material. It kind of wears off after living with it for a few years though. Some trees continue to cooperate and develop into nice things to have around. Others are just a pain in the rear. Time will tell...
By the way, you may be finding out why this species isn't well like for bonsai. Hard pruning can cause die back. I'd wager the top two third of these trunks are dead...or won't last a year or two.
