I like the panels. Is there anything inside the pocket to keep things from hitting the door skin itself? I would be worried a little if something inside the door would move around and dent the door. Looking good however.
I would line the inside of the door skin with either left over tweed from the walls or grey carpet. It would be just on the flat part of the skin, not down in the bottom of the door where it may collect any moisture that may get in there.
