That's some gorgeous wood and you do beautiful work.
But if I may make two observations...
The squared off headstock is very "plain jane." Have you ever given any thought to carving it at all? Many luthiers make a distinctive headstock part of their trademark.
I really like slotted headstocks but the outer strings (g, A) should wind toward the outside of the headstock, and the interior strings (C, E) should wind toward the center so that they're not crossing over each other. Or maybe that's just the classical guitarist in me thinking what I feel is better aesthetically.
