The angle a branch leaves the trunk should be a constant theme in most trees, at least in my mind. The lowest branches should be a little lower, the upper branches should be a little above the plane the lower branch comes of the trunk. But the basic theme the differences in the angle should only be incrementally different between the upper and lower parts of the tree. In the 2019 photos, the angle of the first branch was changed to look more sharply below horizontal. The angle of the upper branches are so different that they don't blend, like the upper and lower parts are 2 different trees. I'd bring the lower branch angle up just a bit, to harmonize better with the upper branches.
I would also allow all the branches to lengthen and expose the areas where they join the trunk. Especially if the corking effect has begun spreading out onto the branches. You have done an excellent job of keeping foliage in ''tight'', but perhaps, especially with the longer needles, letting the whole tree get looser, might harmonize the design better.
These are just my thoughts. Your tree is better looking than any of the corkers I have. I only offer these as suggestions. I do not claim to be an authority on pines, or cork bark pines.
