Take photos from the same plane as the upper rim of the pot. Looking down at the tree, the sense of depth and proportion is distorted.
But the tree already has a style. It is more or less "windswept". Easiest would be to continue to develop the tree in the style it currently has. It has relatively little foliage at the moment. I would let it grow at least one year, to fill out.
For better styling advice a set of photos, with neutral background, no lawn or shrubbery behind the tree to make viewing difficult. The camera lens should be level with the plane of the upper edge of the pot. The camera should be far enough back to encompass the entire tree. One photo every 90 degrees, so we see all sides. Then you will get better styling advice.
Not a bad tree at first glance.
