One possible niggle; wouldn't the ground floor outside door not be a security risk? I thought the whole door up high thing was introduced to reduce the risk of baddies breaking it down. Originally, the access would even have been by ladder or (collapsible) wooden stairs.
Or was this a deliberate choice to increase playability?
Actually I based it on historical builds. The ground floor door was usually the stable entrance where cattle was housed during the night.
The real security risk is the stairwell that runs into the ground level. But this too was observed by me in historical builds. Perhaps the stable door was deemed defensible enough placed in a corner between to walls where defenders could pelt anyone attempting to breach the door with arrows, bullets and boiling stuff.
And of course a stairwell is also easly defensible, although this one admittedly runs the wrong way around for that. This one turns left while it should turn right, preventing climbers from using their shields efficiently.
