My opinion:
Unless someone enters with an even better MOC in the large division, the BSB is probably yours !
Possible improvements:
I am in no position to give advise to such a great builder, but I will to do so anyway!
1) I really wouldn't use any kind of helmet for the soldiers, but you already know that and you stated you don't have enough hats for everyone...maybe hairpieces for one or two could do (like they came out of bed after an alarm)? Or take some tricornes awy from your pirates and give them helmets...
I THINK it might look better, but I am not sure, it would look more historical though, and of that I am certain.
2) I would add some flags and a "ruler/the King you are referring too,as I did not spot him" to the castle/tower/city, make it look more like a "governors citadel". Especcialy because of the big cannon you placed there. That one could use at least one more minifigs BTW (normally they need 6-8 crewmen, but since it's Lego I would add only 2-3)
DNL, big

from me (yes, I used both hands

).
This is, so far, a winner.
