You obviously have a decent eye for design and you have made a good start with this tree. Give it a couple of years to develop. It looks a lot like a Shimpaku Juniper or at least one of the Chinese Junipers closely related; good choice. If you can keep it alive and healthy you will have crossed a major boundry, that of keeping a tree in a pot alive. Then you will be able to conentrate on artistic development. From my point of view I think the tree, as potentially nice as it is, in the near future you will find the tree to be conflicted. The problem manifests it'self with the junction of the two major parts of the trunk forming a kind of sling shot. Been there done that. Eventually I think you will want to remove one or the other and design the tree from there. That decision is yours to make from what your eye sees and your perception of what a bonsai should look like. I don't see you having to make that decision in at least three years, and would probably be foolish to do so any sooner. My first conflicted tree correction took me twenty years to make.
