Ed, Vance is 100% right. This tree needs heavy fertilization, then some growth, followed with constant pinching of the foliage. You need to promote growth closer to the trunk, if possible. The best way to create good shohin or mame is to allow trees to grow, THEN cut them back.
But you have a good eye for a little tree with a lot of potential. You just have to remember that it is MUCH harder to produce a tiny tree that projects the same ancient image as does a 3-foot tree of the same species.
I agree with jkl on everything he has to offer here except the part about "constant pinching". Ryan Neil says ABSOLUTELY NOT when it comes to pinching junipers. He said that in the 6 years that he apprenticed under Kimura, he never once pinched a juniper. He recommends cutting back to nodes to maintain shape, promote backbudding, and adding density to the foliage. The one exception that he allowed for pinching would be before a show in order to perfect a silhouette. Pinching (and especially constant pinching) will result in weakening of the tree.
I know that this is contrary to everything that we have read about juniper care in books, but I think I'll take Ryan's word and his 6 yrs working with arguably the most accomplished bonsai master in the world as justification for taking it.
Compelling argument, but without details it is difficult to truly understand what he is saying. Any clearification? Sometimes we in bonsai run into a conflict of terms saying one thing but meaning another.
@ Fore, are those two branches in the open? If so maybe they have been weakened by either cracking some of the bark when bending or spider mites maybe. It does seem odd that such a small area would not thrive as well as the rest of the tree.
