As a "practical" engineery type of person my initial thoughts here were rather unartistic! This might be pedantry but the access routes and the site entrances are offset from each other. One or other of these came first - and the second would have followed/aligned with the first ?? If this were urban then other factors would mess the situation up over time but that isn't the case here...
It also struck me that the entrances are too wide? If someone puts in the effort to build a wall with that many towers, then....
I'll lay off now! I'm really looking forward to seeing how this develops!
(Yes, I'm a engineer in the defence industry but I confess that we don't do castles anymore! More's the pity!)
