This is a good material, but very challenging. It will need some seriously advanced techniques, to bring it to full potential.
Hanging branches are one part of the solution. Usually, a lot of these junipers have only a few branches on the top third, so they have to be brought down all the way, and mimic braches on the way down. You just need a few years' worth of growth, because right now the branches are too short to form those hanging branches. But you can start bending them now, in the right direction.
One caveat when bending the branches downward: make sure that the tip of the branch is bent upward. This way, they don't lose strenght, and grow much faster.
The other thing you can do, concerns the last portion of the trunk. It can be made into a branch - a very important branch. But right now, it's too thick to be bent downwards. At the current position it is useless, because it is a continuation of the trunk. So, what you have to do, is to separate the live vein from the wood, wrap it with raffia, and THEN you can bend it downwards, creating a nice branch. It is a very difficult technique, and you can easily kill the branch if you don't protect the live vein. But if done correctly, you create a branch of major importance. Mind you, that I've never done this, although I've seen it done many times in Japanese publications. And I would certainly try, if given the chance.
