I actually don't have any established bonsai yet
Here is the umbrella tree I am working on now:
I cut it back to make it branch a week or so ago. It is actually showing some signs of new growth (bulges coming around top of it where I cut it)
It didn't have any branches at all so I had to cut it to make it branch. In a couple weeks it is going in my bonsai pot.
Then I am putting it in this pot:
Very nice plant

Hope it does well for you.
I am hoping to get a pre-bonsai like what you did and try it that way. I am also going to be doing some cherry trees form seed if I ever get them in the mail
