I like the second photo as a nice front. The apex, to me , seemed a little large.
Ha, I'd wire it poorly, trying to compress the top down, or just kill it by removing it completely.
Then, I would reduce the large branch on the right, thinning enough to be able to frame the rock and the nice deadwood. But by then, I already killed it!!
But if it made it that far, I would turn it anti-clock-wise, just a few degrees, so the space between the trunk and rock is less prominent. Easy, cuz' I didn't actually "work" it.....should have thought that first.....
Maybe even try to get the apex lower than the cool point on that stone?
Of course, I would be total chickens#!% to even try anything I just said.....
Carry on
