Nathan,
I would do two things right away to improve your tree.

First, I would tilt it all the way to the left, the trunk forming an angle of approx 30degrees with the horizontal ground.
Then, I would chose the first branch on the right as the leader, cut off the left branch, and wire the current leader to become the first branch on the left side.

Tilting the trunk adds more movement to the design.
Cutting off the left branch will correct an obvious flaw, namely having three equally thick branches growing from one internode.
This is not a flaw if it happens towards the tip of the branches, but it doesn't look good if it involves the main branches.

Right now the crown is too symmetrical and the main branches all grow from the same point.

As soon as the lavender recovers from the initial styling, you can start drastically cutting back the tips of the branches to encourage secondary ramification.

Make sure that you don't do major restyling and root-pruning at the same time (unless you already have a lot of experience).
I've lost a few trees doing that.

Good luck,
