A few thoughts, just random ideas not a complete plan.
- tilt your tree the other way so that the trunk doesn't come almost straight out of the soil. This also might help hide the reverse taper where all of the branches come off the trunk.
- lose the "branch" at the top of the tree growing away from the cascade
- cascade branch is very straight and rather uninteresting (the top is much more interesting). I would either cut it back to semi-cascade, or wire a lot more movement
- I would at least consider completely losing the cascade and making this an upright plant.
- Compact! Losing the top "branch" will help, as would wiring movement into the cascade or cutting to semi-cascade. Wire more movement into the branches on the top, bringing them closer to the trunk.
You have a few different options, but right now this plant seems to be pulling in a couple different directions. It needs some consolidation, more cohesion. Don't be discouraged because this looks like it can be turned into something very interesting. But it will take a plan/vision, and perhaps a bold move.
