Thanks for posting the detailed photos. I can see now why you want to finish it further, the top edge would annoy me too. Though I would probably just sand it. I would cheat with the pickguard too, glue two screheads flat over the holes rather than print a new one, and just trim that excess foil back with a sharp blade.
Overall though, it still looks the business. Now it just depends on whether you want a perfect finish, or a "post manufacture pre-reliced" look.
