Very nice! It might sound scary but removing that central downward branch that shears down through the apex and crosses the trunk could open the tree up and reveal that awesome trunk line. For such a nice and curvy slender trunk line, it would be a shame to hide it. It looks like something very interesting is going on in the upper right quadrant behind that crossing branch and foliage, and I'm guessing it is something good. It is not my intention to impose or be intrusive, of course (your tree is stellar, and I like the design thus far), but I love to see trunk line that warrant their exposure. Flaunt it if you've got it!
