Nice Friend!!!
Crab Apples are a blast to work with and are overall very forgiving. It looks happy, but what do you know about the overall health of the tree? Reason I ask is that before I think about direction, I want to make sure the tree is healthy. In looking at future direction, the first pic looks like it would make a nice split-trunk style. The other pics, from what I can tell, makes the base look more sqaure than tapered, but that can be just the angle of the shot.
