With the drastic initial bend, you might want to look into making it into a cascade or semi-cascade. The drastic initial bend is an integral part of a cascade design and something that is missing in a lot of cascade or semi cascade trees. You've got a great start on that. The cascade or semi- cascade design would involve not-so-drastic bending on the remaining trunk and minimize the work on the branching.
If you try to push the trunk into more upright contorted design with additional drastic bends, you might as well remove the branching and start over, wiring new branches into more drastic shapes as they grow. In the end, however, that is probably going to result in a tree that looks kind of strange, IMO.
