Hm.. Dificult tree. It is a shame there is no foliage on the first part of the branches near the trunk. You now cannot cut back to where you ideally would. I probably would dig down a little to check where the roots of the tree are, and what you can do rotating the trunk a little. Then think the top. Let the bottom grow and hope for some buds to form around the first section of the lower branches so you can cut back to that.
The second image shows the tree:
