Hallow said: once I get it going I will. I tried a bonsi with the same plant before but ended up putting it a normal pot. But I'll start it again.
This is the one I'll be using
Okay what I do to start it mine is removing a lot of leaves around the base of branches to reveal the branch structure that way you can have a better idea what to either remove, prune to develop branching, or wire. Also remove all the largest leaves, you want to promote small leaf growth also. Basically thin it out heavily! This will also make it able to be wired, the way yours is now there is no way it can be wired.
Do you have any fine tipped scissors? Here's two scissors of mine, the ones on the left were a gift from my master I studied under, the ones on the right are student scissors I taught classes with. If you don't have a pair I would be happy to loan you the white handled one.
Edit: I. Regards to the pot I think it's best to begin to style it first and let it Reestablish whole it happily is comfortable in that pot and then repot it into its smaller pot after. It will do better this way.
