I think this could be the frontStart off by picking a "line" or "front" and go from there, be it Multi trunk or thinning down to less.I sorta like this type of line but you can follow your own desires.Also take off the really thick branches higher up because they will never look right.This is a quick virtual with the supplied pics ,have fun..

you should look into good repotting times for the specific tree.Repotting will be my project for the day
If you know what you want to chop and wire then you could do that now, or you can thin it out just a bit, maybe get rid of that low branch as a minimum.
You can do it over the next few days slowly if you like so you don't rush any decisions. If you leave it alone until next spring/summer you may even get another flush of flowers this year and then cut back after that.
They are fairly versatile.
