Well didn’t get much advise on the styling this time around. Pretty sweet little mugo if you ask me and wanted some other opinions even though I had a plan in mind.... sorta
Been there and still doing that, myself.
So it is time to figure out why it doesn't work. What I've noticed about root over rock stylings is that the rock tends to become the trunk, visually. The tree you started with had a nice little canopy in (more or less) the standard scalene triangle shape. A scalene triangle canopy shape is per 'the rules', which means it won't be the focal point - it will be accepted because it is what is expected. Had you somehow cleverly lowered it a bit so that a little peg of a trunk above the rock wasn't visible, it might have looked like a small tree with a thick, powerful trunk. Maybe it would have taken another season or two to get the canopy in balance with the trunk-rock, but that would be all that was left to do and then maintain it.
That idea may leave you unsatisfied and that is okay. But, in addition to a non-scalene triangle canopy, you've also brought a low branch across the rock-trunk. This is a nice way to disguise a long, thin, taperless trunk, but you've got a nice fat tapering rock and you've obscured it.
All in all, I think you have minimized the strong points of your tree and emphasized the weak ones. So, I suggest that you get straight in your mind, why you thought this was such a great little tree when you bought it. Now that you are where you are with it, do your best to determine why you think it has gone wrong and what it will take to deal with it and get on a track that is making a tree that will smile back at you.
