The neck fit in the pocket is pretty good, although the angle means there's a bit of a gap at the top of the pocket. Options would be to slightly angle the butt of the neck heel so it sits flush against the pocket (but this would mess with intonation), or maybe glue a small angled shim at the top of the pocket (or on the neck heel itself). Need to tweak the neck angle first before deciding if it's necessary.

And, the expected slight gap from the doming on the base of the neck heel:
