You did an EXCELLENT JOB. There is no such thing as totally predator proof, but you come very close. The predators you list should be well deterred. If you did encounter bears, well, they can overcome most things short of Alcatras. The other lil devils are the weasels martins, and mink type predators. Hope you don't have those in your area. About the only thing I would add would be a Hot Wire Electric fence. Wait and see if you need one. The most important is to look up your chickens for the night. That is when most predator attacks occur.
WISHING YOU BEST
