I previously left feedback on the sept and septry that has not been addressed but the melons have been removed. Not sure if the following feedback applies to Jeff or KDS.
The main issue is with use of different rooms. Why is the sept structure stuffed full of beds in that level above the office? Why is there an office connected directly to the sept, rather than a sacristy, refectory or other public area/facilities relevant to the sept? Why is the fireplace entirely made of smooth river pebbles? wouldn't it make more sense for the block mix to be bricks of some sort?
is the western wing of the septry (perfect place for cells/bunks for the brothers/sisters) empty because the sept is stuffed full of beds?
Can the (presumably) masters chambers be revisited so that the windows and ceiling height work together (as I built a model of before and has now been removed, having not been implemented as suggested (at least copy it above or something so there's some before/after) and general furniture having a consistent level of wealth.
Is there a reason there are enormous fireplaces in the northern wing (common room, corridor-like rooms that could be bunkrooms/cells) and tiny fireplaces in the most richly furnished rooms? Also why are they nice, imported brown stone but the chimneys are grey local stone?
Expand the scriptorium to the upper floors of the southern wing. They really need light to work, so the library/room with the table surrounded by bookshelves is virtually unusable. You could improve the light situation by expanding the scriptorium to occupy the second floor as well. Having libraries/scriptorium above the ground floor is the most effective way to keep books safe from damp and flooding.
In the place of the dark library bit, you could have a porter's lodge or something with an arrow slit through to the entrance way.
If the eastern wing ground floor room is a body washing place, put a stranger's symbol or something cos otherwise it looks like a medicine room, herbal tea making spot or otherwise.
Why are there stools in the dark in the masters bedroom? Also use the design of the scriptorium desks for the masters desk. It shows some more consistency and looks better with the hoppers, while also not seeming so much like a shelf.
Chests are overused in the masters apartments. There's other things the space could be used for, test around a bit.
Yet again, lift the main windows in the masters chambers up a block. they shouldn't be at the floor level. Also the whole point of moving the floor up and making it 2 blocks thick was so that you could put in nice carpets or interesting wooden floor patterns. This evidently didn't happen.
In the castle:
Use sand, not snow, for spilt flour. Snow looks like spilled salt more than white flour which ofc is a warm white, rather than a cool white colour.
Southern Drum - Don't use dark wattle and normal wattle in the same room for virtually the same function. the normal wattle looks better with jungle anyway.
The stone ceiling is v strange. either commit to a proper arched vault or make proper supports. A hopper and wall column isn't going to hold 9x9 of stone bricks. The rest of the ints are good.
Southern storage - Make sure there's some block variation in the roof. It doesn't all look good as basalt cobbles. Add some northern wood or bedrock
I'd put some windows on the servants quarters, even small tiny 1 1/4 stair holes to allow some air in. Its still the stormlands and it apparently gets v hot and humid in summer.
I think the wooden part of the staircase next to it could be a bit better executed. Maybe have a look around at a few constructions over the server to find some good examples. There might be some at the vikary mine or on the westbrook-uffering bridge.
Southern thin tower - now that is a vaulted ceiling in the bottom floor! thats nice. Good vibes. Anyway, I'm liking this tower but switch out the fancy table block in the barrack for a pot or endcrate + button. its too fancy with its parquet top.
Stables - these really need more ventilation. I know its wet and rainy but these would stink soooo much. Spread fresh straw on the ground to help soak up water. you don't want the animals getting hoof-rot, which the wet pebbles would only encourage.
Cellar - is fine
Forge - cool ints! I'd still add a window or two though. v hot.
Chicken coop - always good in a castle
.
Guard's hall attached to tower - is good.
Eastern thin tower - don't like the room in between the guards hall and the wall walk. It should have a 2x2 table with more stuff on it and something in the opposite corner too. feel v empty and sterile. I don't think you need a big table at the very top of all of these towers, especially as they'd have to build it piece by piece handed up the ladder
