I hear you about the predators. Ours still only range with supervision. Electric fencing (and dogs and vigilance) helped us carve out a chicken yard so they get plenty of exercise. We do close them in their runs when everyone leaves, for another level of security. I still don't trust bobcats and foxes not to find a way around the electric when we're not here.
You'll find what works for your space and your biddies as you go

Your pictures show that you also have the best part of the whole setup covered: human seating near the coop! Nothing better than sitting with the birds.

@3KillerBs' point about the overhang. We always do a foot or more. Might seem like a lot until the first storm that gets rain or snow on your chickens. Ventilation's evidently crucial for respiratory health, but of course any openings in a building create issues (you can see my little plastic rain break tacked over part of the ventilation after a couple windy storms overcame this overhang). We did the same style ventilation on a 6x4' coop in the background of this photo, but with more overhang, and the windward window closes for cold/windy days, which is the jam.
Some people border the bottom of the overhang with a soffit/rake for more of a shield from the weather, and we may do that next. There's a great post somewhere on BYC about installing these, but I absolutely couldn't find it, sigh.
Our little coop was a rush job, and then temporary-to-permanent set in, so it still needs finishing touches like trim, but it's so functional. With yours, I think you'll really enjoy the height of the coop and how big you made the door on the back so it's easy to access the inside of the coop.
Lastly, have you thought about adding a hardware cloth apron around the outside of the run? Great use for your scraps and very recommended to keep those foxes out. If you have raccoons, I'd add locking latches to the doors, too.
