Asoka (saraca Indica) tree (5 years old)

These are pictures of a Asoka tree (Saraca Indica) I have been training for the last five years. It was land potted for the inital few years, then when I had to move to the apartment , I transfered it into this cement pot. But to say honestly, I bought this tree when I didnt know much about this art (even a little now too !!), and I almost forgotten this tree, and it has been under the maintenance of my father in our terrace. I started to see this recently when I decided to take this hobby seriously, and this tree's present looks was given by my father by bending down the upper branches roughly with some wire. I think that I have to clean up the routes and do a rewiring to this to give much cleaner look and to trigger the growth, but my father somehow doesn't like me to work on this tree. I may either do something to this or will leave it as such in its own way of styling. But I will do the root prunning and change the soil shortly.
