Hi Ginny
Regarding the tree going in two directions, I find it difficult to explain, other than knowing "the flow" of the tree should be harmonious, and asymmetrical shapes "look" better than symmetrical ones. Broom style tends to not have a fork so low...
I found this set of "rules" that might help....but I'd go look at lots of books on bonsai and successful grower's works to get a feel for what can be successful and what might not be.

On the other hand, if you're wanting to have a natural looking tree that you might see out in a huge park, where it can grow its full umbrella shape, then that's fine too! It's all about personal preference, imho.
Agree with Lane about doing the layer, I'd wait til next Summer.
